To remove or replace physical volumes in a volume group for maintenance purposes, use SMIT or the chpv command.# reducevg <VGname> <PVname># rmdev -dl hdisk<n>

Replace the disk...# cfgmgr -v# lspv# chdev -l hdisk<n> -a pv=yes# extendvg <VGname> <hdisk<n>

Mirroring rootvgIf you do not mirror the root volume group, you have a single point of failure. Always mirror rootvg! I have seen too many unnecessary system rebuilds because rootvg was not mirrored. Mirroring rootvg is a straightforward process and consists of the following steps, in which we are going to mirror rootvg to a new disk called hdisk1:1. Add hdisk1 to the rootvg for mirroring: # extendvg rootvg hdisk1

2. Use this command if all the rootvg logical volumes were created properly: # mirrorvg rootvg3. Or (if a problem was encountered) manually mirror rootvg and do not mirror the dump device (lv00 in example):

# lsvg# lsvg -l rootvg# lsvg rootvg

4. Mirror each logical volume:# for N in $(lsvg -l rootvg | grep syncd | awk '{print $1}' | grep -v lv00)> do> echo $N> mklvcopy $N 2> done5. Sync the volume group:# syncvg -v rootvg# lsvg -l rootvg

6. Configure the boot devices:# ipl_varyon -iPVNAME BOOT DEVICE PVID VOLUME GROUP IDhdisk0 NO 00001047375ac230 000010472822f021hdisk1 YES 000010472822e532 000010472822f021

The mirrorvg command does all of the mklvcopy commands under the covers for you. Since disk quorum was disabled, we must reboot the system for the changes to take effect.

How to Change Kernel Mode of IBM AIX 5L (5.1) for more information.

There are three kernels available in the /usr/lib/boot directory: unix_up 32-bit kernel for uniprocessor systems unix_mp 32-bit kernel for multiprocessor systems unix_64 64-bit kernel for 64-bit processor systems

The following example provides the commands to run to enable the 64-bit kernel after system installation:

# ln -sf /usr/lib/boot/unix_64 /unix# ln -sf /usr/lib/boot/unix_64 /usr/lib/boot/unix# bosboot -ad /dev/ipldevice# shutdown -r

After the system has rebooted, it will be running the 64-bit kernel. To reactivate the 32-bit kernel, follow the same procedure, substituting unix_up or unix_mp for unix_64, depending on your system type.

Once the printer driver is installed, you can proceed to add the System V printer to the system. There are three steps to enable the printer. The lpadmin command is used to add the printer:# mkdev –c printer –t hp4V –s parallel –p ppa0 –w p# lpadmin -p hp4V -v /dev/lp0 -D "Hewlett-Packard LaserJet 4/4M"After the System V printer has been added to the system, you need to use the accept command to allow the printer to accept print requests:# accept hp4V

The last step is to enable the new print queue using the enable command:# enable hp4V

To define the print queue on the remote client, use the following command syntax:# lpadmin -p <client_printer_name> -s <remote_pr_server>!<remote_pr_queue>

The System V filesets that are installed by default include the following:bos.msg.en_US.svprintbos.svprint.fontsbos.svprint.hpnpbos.svprint.psbos.svprint.rtebos.terminfo.svprint.data

HMC: List partitions authenticated by RMC/opt/csm/bin/lsnodes -a Status partition01 1 partition02 0 partition03 1 Where 1 means LPAR is activated and authenticated for DLPAR; 0 means otherwise. If the LPAR is activated and still shows Active<0>, you could have either network or hostname setup problems. If you have just rebooted the HMC, wait for a few minutes. If nothing changes after that, check your hostname/network setup in Setting up HMC/partitions hostname and network.

(In this example, LPAR 002 is being shut down, and LPAR 003 is not activated because it is at AIX 5.1.) If you're missing some active partitions or some partitions are reported as Active<0>, your system probably still has a network/hostname set up problem. See Setting up the HMC/partitions hostname and network. (If your LPAR is Active<1> but the GUI is still not DLPAR capable, do a rebuild to get around this problem. See the Appendixes in this article for more information.) If you still can't get partitions recognized by DLPAR after verifying the

checklist, contact IBM service personnel.

Steps to create a Syctl application

Task :- User siju (kerberos principal siju.adm) should get the permission to start a subsystem by executing the command substart. Permission should not be given to other users.

1) Create the client application substart in /usr/bin directory of cws with following contentsif [ $# -gt 2 ]

then echo "Arguments exceed the limit"exit 1

fi/usr/lpp/ssp/bin/hostlist -n $1 | /usr/bin/sysctl -c - substart_proc $2In the above script if condition will check for the number of arguments and execute procedure

on corresponding host

2) Change the mode to executable chmod 755 /usr/bin/substart

3) Create server application substart.tcl with a procedure substart_proc with following contentscreate proc substart_proc {SubSystem} AUTH {global SCUSERif [ aclcheck -f /etc/substart.acl $SCUSER ] {

exec /etc/substart.srv $SubSystemreturn} }

if condition in the above example checks for kerberos user in the acl file /etc/substart.aclIf the condition is true it execute the command /etc/substart.srv with arguments passed bysubstart command

4) Create the script substart.srv with following contentsstartsrc -s $2This script execute the command startsrc with the argument passed by the substart command

5) Change the mode to executable chmod 755 /etc/substart.srv

6) Create acl file substart.acl with the entry for user siju#acl#_PRINCIPAL siju.adm@CWS

7) Add the application to the sysctl by adding following line to sysctl.conf fileinclude /etc/substart.tcl

8) Distribute the files to all nodes

pcp -av /usr/bin/substartpcp -av /etc/substart.tclpcp -av /etc/substart.srvpcp -av /etc/substart.aclpcp -av /etc/sysctl.conf

9) Restart the sysctld daemon to get the new information on cws and on all nodes10) Get the kerberos ticket for user siju and execute following command

substart 3 lpdThis should start the lpd daemon on node 3

11) Try the above command with any other kerberos ticket. Result should be negative

Network Install Manager (NIM)1. First, create a /tftpboot filesystem before running smitty nim_config_env. To create the /tftpboot

filesystem and install the NIM software, use the following command sequence:# mklv -y 'lvtftp' rootvg 1# crfs -v jfs -d lvtftp -m /tftpboot -A yes# mount /tftpboot# chfs -a size=120000 /tftpboot# df -k /tftpboot# installp -qaX -d <device> bos.sysmgt..nim.master bos.sysmgt.nim.spot# smitty nim_config_env

2. Create a /tftpboot filesystem and install the NIM filesets using the preceding command sequence.3. Configure the NIM Master from CD-ROM using smitty nim_config_env.4. Define the client machine(s) using smitty nim_mac.5. Create a mksysb image and define a mksysb resource using smitty nim_res.6. Install a stand-alone client from the mksysb image using smitty nim_bosinst.7. Boot the client.

NFS DaemonsThere are a number of daemons that need to run on both the client and the server.Client

biod Improves NFS performance by filling and emptying the buffer cache. By default 6 biod daemons are started however this can be changed to improve performance. These are started in the /etc/rc.nfs file.

rpc.statd Allows the remote procedure calls

rpc.lockd Handles File lockingServer

portmap Provides a standard way of looking up the port for a certain application. The application registers with portmap, then portmap listens on the appropriate port. When a client communicates on the NFS port, portmap replies with the real port number of NFS. Portmap is included in the /etc/rc.tcpip file and must be started before inetd and the RPC servers so that it can accept the registrations.

nfsd A server daemon that handles the client requests for file system operations. Each daemon accepts one request at a time, however once it has passed the request on to the kernel it is free to accept a new request. Bu default 8 nfsd daemons are started, however if the server is a busy nfs server then a value 50 to 100 might be more appropriate. These are started from /etc/rc.nfs and are under the control of SRC.

rpc.mountd Accepts a mount request from the client and allows the export if authorised.rpc.statd Allows Remote procedure callsrpc.lockd Implements file locking

NIS Servers and Clients Configuration# smit mkmasterHOSTS that will be slave servers [slave1,slave2]Can existing MAPS for the domain be overwritten? yesEXIT on errors, when creating master server? yesSTART the yppasswdd daemon? noSTART the ypupdated daemon? noSTART the ypbind daemon? yesSTART the master server now, bothat system restart, or both?

# smit mkslaveHOSTNAME of the master server [Master]Can existing MAPS for the domain be overwritten? yesSTART the slave server now, bothat system restart, or both?Quit if errors are encountered? Yes

# smit mkclientSTART the NIS client now, bothat system restart, or both?NIS server - required if there are no []NIS servers on this subnet

To stop, start, or check status of the NIS client ypbind daemon, run the following commands:# lssrc –s ypbind# stopsrc –s ypbind# startsrc –s ypbind

NIS Packages - bos.net.nis

Starting NIS ServicesLike NFS, NIS is managed as a subsystem under AIX. NIS daemons are started using the SRC startsrc

and stopsrc commands. The /etc/rc.nfs script contains code to start up NIS services before bringing up NFS.# startsrc -g nis# stopsrc -g nis

The NIS daemons are as follows:ypserv NIS server daemonypbind NIS server binding manageryppasswdd NIS passwd update daemonypupdated NIS map update invoked by inetdkeyserv Public key server daemonportmap RPC program to port manager

NIS PLUSNIS Packages - bos.net.nisplus

To create NIS+ master servers and clients, invoke the SMIT FastPath smit nisp_config. AIX also provides setup scripts to set up NIS+: nisserver, nispopulate, and nisclient.

The following table contains a list of common NIS+ commands to manage different NIS+ components.

Command Descriptionniscat Displays object properties of an NIS+ tablenisls Displays the contents of an NIS+ tablenisrmdir Removes an NIS+ object from a namespacenisrm Removes NIS+ directories and subdirectories from a namespacerpc.nisd The NIS+ daemon; provides NIS+ servicesnisinit Initializes a workstation to be an NIS+ clientnis_cachemgr Starts the NIS+ cache manager daemonnisshowcache Displays the contents of the shared cache filenisping Pings the replicas and prompts for updatingnislog Displays the contents of the transaction lognisgrpadm Creates, deletes, and performs miscellaneous administration operations on NIS+ groupsnisdefaults Displays the seven default values currently active in the namespacenisaddent Creates NIS+ tables from corresponding /etc files or NIS maps

Starting NIS+ ServicesLike NIS, NIS+ is managed as a subsystem under AIX. NIS+ daemons are started using the SRC startsrc and stopsrc commands. The /etc/rc.nfs script contains steps to start up NIS+ services.# startsrc -g nisplus# stopsrc -g nisplus

NIS+ daemons are as follows:rpc.nisd NIS+ server daemonrpc.nispasswd NIS+ passwd update daemonnis_cachemgr NIS+ cache manager daemon

Sendmail FilesThe sendmail MTA uses the following files for configuration and data:/etc/mail/sendmail.cf Sendmail configuration file

/etc/mail/aliases Mail aliases/etc/mail/aliases.db Compiled alias file/etc/mail/sendmail.pid PID of sendmail daemon/etc/sendmail.pid Link to sendmail.pid file/etc/mail/statistics Mail statistics

The sendmail program accesses configuration file information from a compiled version of the /etc/sendmail.cf table. To compile a new version of the database, use sendmail with the -bz flag.# /usr/lib/sendmail –bz --- Compile a new sendmail.cf database

sendmail accesses alias information from a dbm version of the /etc/aliases table. To compile a new version of the /etc/aliases table, use /usr/lib/sendmail -bi.# /usr/lib/sendmail –bi ---- Create new alias database

The sendmail program is invoked as a subsystem from the /etc/rc.tcpip script. The AIX sendmail automatically compiles the /etc/mail/aliases and /etc/mail/sendmail.cf files when it is started. If you are running a non-IBM-supplied sendmail, you may need to force a compile of these files as part of the start-up. If you update any of the configuration information while sendmail is running, refresh the sendmail subsystem by issuing an SRC refresh command or by sending the daemon a SIGHUP.# refresh -s sendmail# kill -1 'head –1 /etc/sendmail.pid'

The basic startup flags for sendmail should invoke sendmail as a daemon and specify the time in minutes between mail queue scans for postponed messages. These flags are -bd and -q<time>.# /usr/lib/sendmail -bd -q30m # Start and scan mail queue every 30 minutes

To stop the sendmail daemon, use the SRC stopsrc command or send a SIGABORT to the daemon.# stopsrc -s sendmail# kill -6 'head –1 /etc/sendmail.pid'

To restart the stopped server, use the SRC startsrc command. (Note that startingsendmail with startsrc requires an additional parameter.)# startsrc -s sendmail -a'-bd -q30m'

To check the status of the sendmail daemon, use the SRC lssrc command.# lssrc -s sendmail

To display the set of supported signals, use the -l argument of the kill command:# /bin/kill -l

TSM Server Management:Defining Database and Recovery Log Sizes:

Size in default:

DB Volume (db.dsm) – 17 MBLOG Volume (log.dsm) – 9 MB

Format and define a 500MB DB and 25MB Recoery LOG vol. And extend them by

define dbvolume db2.dsm formatsize=500define logvolume log2.dsm formatsize=25

extend db 500extend log 25

Increasing Disk Storage Pools:

By default,

BACKUPPOOL backup.dsm (8 MB)ARCHIVEPOOL archive.dsm (8 MB)SPACEMGPOOL spcmgmt.dsm (8 MB)

To create a 100MB volume named sbkp01.dsm in BACKUPPOOL,

Define volume backuppool sbkp01.dsm formatsize=100

Adding Administrators:

Creating a user named mark with password Missouri and adding him to system class

Register admin mark MissouriGrant authority mark classes=system

Adding Backup-Archive clients:

Registering a node Mercedes where u have already installed TSM client with password montana

Register node Mercedes Montana userid=none
