VCM DB backup for VMAX
VMAX/SE 7.0.1
I have a couple of SYM for which i take vcm db backup daily basis(symmaskdb backup -f fname). Now there is a VMAX added to the environment.
Should i take the similar backup for Vmax? is it needed/helpful since Vmax does not do any specific masking as compared to SYM??
Your advice is appreciated.

Hi SKT,
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
Thank you

The backup file created by symmaskdb and symaccess are exactly same. So does not make a sense interms of which command we use .

The difference lies here...
symmaskdb - works on VCMDB concept.
symaccess - works on Autoprovisioning Groups concept.
Autoprovisioning Groups are not supported on Symmetrix DMX arrays running
Enginuity 5773 and earlier.
symaccess, provides all the storage provisioning requirements for
Symmetrix V-Max arrays running Enginuity 5874.

the symmaskdb command don't work on VMAX, you can only use the symaccess command

yep, symmaskdb backup command works on Vmax but it will not work for any masking operations.
