How do I list VVs exported to hostset using CLI?

[kherrmann]

Is there a way to list the VVs exported to a hostset using the CLI? I'm trying to untangle our mess of exports, to corral them into a single VVset/Hostset configuration.

Mainly, I want to compare which VVs are exported to a host directly vs. through the use of a hostset.

Did you have a look at showvlun already?

Yeah showvlun will be your command.

I recommend against using both hostsets and vvsets together. I prefer to stick to just host sets, and avoid vvsets, reason being is greater control over lun # assignments.

I also recommend a good VV naming standard. We use hostname_LUN#_briefdescription, and we make sure the export matches the LUN# we labeled. This works really well for requests to grow/decommission a lun, makes it quick and easy to find the exact target to grow/decommission.


examples:
NTEXCHANGEP1_1_DAG1
AIXORACLEP1_7_ASM
AIXORACLEP1_1_ORAvg
NTSQLP1_44_HR.DB
NTSQLP1_45_HR.LG
NTSQLP1_46_FIN.DB1
NTSQLP1_47_FIN.DB2
NTSQLP1_48_FIN.DB3
NTSQLP1_49_FIN.LG1

Its not 100% fool proof, we have had times where a team will request 2 luns of the same size, we will provision it and say LUN44 is for your database files, and LUN 45 is for your log files, but OS teams/dba's can still get it backwards. So the description piece at the end is an optional convenience, and the LUN# should be primary identification used when communicating an action with the host admins.

The descriptions I use allow us to better leverage system reporter to run filtered reports by limiting the report to just LUNs by wildcards in the name.
