'symmaskdb' feature not available for VMAX

Fellow SAN Administrators:

I am pretty sure I am doing something silly. I am trying to run this command on our VMAX to grab all the LUN information for a particular host:

C:\TEMP>symmaskdb -sid XXXX list capacity -host HHHHHH

The output I get is:

Feature is not available for this microcode level.

I may be wrong - but I still have a feeling that I have run this command successfully on this VMAX Array. Please point me in the correct direction. Any other way out to find the list of all the LUNs belonging to a Node? Any input from your end would be most appreciated.

Regards,

KGD.

if you know storage group name:

symdev list -sid 1234 -sg

With VMAX the symmask and symmaskdb commands have been retired.  VMAX uses auto-provisioning, which uses the symaccess command set.  It's a bit different, you create 3 groups - initiator, port and storage, and then combine them into a masking view.

To see what's assigned to a specific host, use symaccess commands to determine which initiator group your host's HBA WWN's fall into (if one exists).  Then check the initiator group to see which masking view(s) it's associated to and what storage group(s) is aligned with it.  Once you do that you can take a look at the storage group to see what you've got for devices.

There are lot of options and parameters so you may want to check 'symaccess -h' and consult the following guides if you need details about what they do:

Solutions Enabler Command Reference

Solutions Enabler Symmetrix Array Controls CLI (there's a chapter specifically on Auto-Provisioning)

Thanks a billion to Dynamox and Pete2C. I was able to extract what I needed the most.

I captured the Storage Group Names with this command first:

symaccess -sid XXXX list -type storage

Then, I ran this command to get the LUN details:

symdev list -sid XXXX -sg SG_HPUX_SERVER_01

The only thing I couldnt get from the output was the "WWID" of each one of the LUNs. But, no biggie - I can ask the UNIX guys to run an INQ and I can get the information from there. If anybody else is aware of a better way to extract with the SYMCLI commands, please feel free to post.

Thanks again.

once you know device id you can run “symdev list –sid 123 –wwn | grep ”
