Storage Procedure for VMAX

How Create Storage Group:

1. A Storage Group is a logical group of Symmetrix devices that are managed together. It is common to assign a storage group to a business application.

2. Storage groups are used both in FAST and in Autoprovisoining. Devices can be shared between storage groups. How ever they can only belong to one storage group that is being managed by FAST.

How to Associate Storage Groups:

1. One or more Storage Groups can be associated with a FAST policy.2. A Priority of 1 (high), 2 (medium), or 3 (low) must be assigned with the storage group at

the time of association3. The devices in the Storage Group are marked as being out of policy. That is because RAID-5

Devices are not part of the 100FC100SATA Policy.4. Since FAST is enabled, the FAST procedure will collect statistics for about two hours and

move the devices as and when the capacity based algoritm is run.

Find list of Data Devices and their Disk Groups:

1. The 9 data devices that will be used in three disk groups.2. symdisk list –dskgrp_summarycommand leads to the following observation:

Devices 1A9:1AB are in disk group 1 with 15K RPM FC drives and are RAID 1 protected. Devices 1AC:1AE are in disk group 2 with 10K RPM FC drives and are RAID 5 protected. Devices 1AF:1B1 are in disk group 3 with 7200 RPM SATA drives and are RAID 6 protected.

How to find List of Thin Pools:

How to Create FAST VP Policy:

Here we create a policy 50FC50SATA_VP that states that 50% of thin device storage associated with the policy must be on the tier RAID5_FC_VP and the other 50% should be on the tier RAID6_SATA_VP.

How to Associate Storage Group with Policy:

1. The storage group sun1_FastVPGroup has all its storage associated with pool

DG2R5FC_Pl at the time it was created.2. Consequently, the association of the storage group sun1_FastVPGroup with the policy

50FC50SATA_VP causes the storage group to be non-compliant.

How to Monitor Configuration Sessions:

1. Before initiating any configuration tasks from SMC it would be prudent to check if other configuration tasks have been initiated by other SMC users.

2. The “All Active Tasks” tab of the Config Session view of a particular Symmetrix will show you if any tasks are currently active or running.

3. Please note that this view only shows tasks initiated by this SMC server. Configurations initiated by SYMCLI will not be seen in this view.

How to Set Symmetrix Attributes:

How to do LUN Migration:

Lun Migration Wizard:

1. The SMC LUN Migration Wizard guides the user through the process of migrating Symmetrix devices from one set of disk locations to another.

2. The wizard also gives the user the opportunity to change the protection type of the devices.

3. Migration of devices can be done using either configured or unconfigured space. 4. Configured space is where the migration of devices moves to an existing set of target

devices. 5. Unconfigured space is where the migration of devices moves to a set of new devices

created from available disk space.

How to do Source Device Selection for Thin Lun Migration:

1. When Thin devices are being moved from one pool to another, we choose Virtual pool migration as opposed to Disk Group migration.

2. After entering the name of a valid storage group containing thin devices, the source devices are automatically entered in the Selected Source Devices window.

How to do Target Selection for Thin Lun Migration:

The wizard offers a selection of thin pools that the selected thin devices could migrate to.

How to do FAST Implementation with SMC:
