VMAX doesn’t have VCMDB for masking. Insted, its using Autoprovisioning Groups.

Autoprovisioning Groups allow storage administrators to create
groups of host initiators, front-end ports, and logical devices. These groups are then
associated to form a masking view, from which all controls are managed.

A new command, symaccess, provides all the storage provisioning requirements for
Symmetrix V-Max arrays running Enginuity 5874.

The masking views, including storage groups, port groups, and initiator groups can
be backed up to a file, and restored from the backup file.

Use the following syntax to backup the masking views for a Symmetrix array to a file:

symaccess -sid SymmID -f BackupFilename [-noprompt] backup

Symmetrix V-Max Approach to Storage Reclamation

Follow the Below Steps for Storage Reclamation from the Vmax.

Step 1: Verify the Masking View Information. The Masking would give us the information about the
current Storage Group(SG), Initiator Group(IG) and Port Group(PG)
# Symaccess -sid 155 list view
The above syntax will list all the Masking View and identify the one you are working it on.
Step 2: View the Details of the Specific Masking
# Symaccess –sid 155 show view d1oraclust_MV
Step 3: Unmask and unmap the Devices. With Autoprovisioing Groups, this is simply matter of deleting the Masking View and the Devices will be unmapped and unmasked automatically. The following is an example if the command.
Caution
#symaccess –sid 155 delete view d1oraclust_MV
Step 3: Delete the Storage Group
#symaccess –sid 155 delete –name d1oraclust_SG -type storage -force
Step4: Delete the Initiator Group
#symaccess –sid 155 delete –name d1oraclust_IG -type initiator -force
Step5: Delete the Port Group
#symaccess –sid 155 delete –name d1oraclust_PG -type port -force

Step 6: Unbind the Devices from the thin Pool.
This step will make sure that we unbind the devices those are reclaimed from the host.

#symconfigure –f unbinddevice.cmd –preview
#symconfigure –f unbinddevice.cmd –prepare
#symconfigure –f unbinddevice.cmd –commit

Step6: Dissolve the Meta Devices
It is advised and to follow to delete the met devices once these freed up. The Intention behind is to have no discrepancy in the data of one server to be presented to other host by reusing the Devices in any form.
# symconfigure –f metadissolve.cmd preview
# symconfigure –f metadissolve.cmd prepare
# symconfigure –f metadissolve.cmd commit

Control and log files locations

lists the network services available from that host

/var/symapi/config/options
the options file contains behavior parameters that can be set to critically change default behavior of SYMCLI operations, SYMAPI calls and their control actions

/var/symapi/config/symavoid
identifies devices to skip over when looking for devices

/var/symapi/config/gkavoid
identifies devices not chosen as gatekeepers

/var/symapi/config/inqfile
lists devices to be added to the symapi database

/var/symapi/log/symapi-.log

Procedure to add VDEVS devices to appropriate snap pool.

1. Create a text file, disable.txt, containing the following line:

disable dev <Your Save Device>:<Your Save Device> in pool DEFAULT_POOL, type = SAVEDEV;

Use the text file with symconfigure command.

1. Add the disabled save device to the appropriate save pool and enable it

Create a text file, adddev.txt , containing the following line:

add dev <Your Save Device>:<Your Save Device> to pool Cam_snap type = SAVEDEV, member_state = ENABLE;

Use the text file with symconfigure command

1. To verify if the devices were added correctly

symsnap -sid 4782 show pool CAM_Snap

Let me know if you have any questions.

What WWN we need to use in the intiator Group PortWWN or Node WWN

When we use node wwn, the wwn logins to the FA and SAN but host will not be able to see the Disk. So use Port WWN in the intiator Group.
