How to get VxVM diskgroup version

If you need to determine the version of a Veritas diskgroup it can be done by two ways:

1. vxdg command:

Execute vxdg list <diskgroup> and look for the version field in the output.

# vxdg list dg_sap

Group:     dg_sap
dgid:      1273503890.14.serv1
import-id: 1024.10
flags:     cds
version:   140 <--- version
alignment: 8192 (bytes)
local-activation: read-write
ssb:            on
detach-policy: global
dg-fail-policy: dgdisable
copies:    nconfig=default nlog=default
config:    seqno=0.1076 permlen=24072 free=24068 templen=2 loglen=3648
config disk disk27 copy 1 len=24072 state=clean online
config disk disk28 copy 1 len=24072 state=clean online
log disk disk27 copy 1 len=3648
log disk disk28 copy 1 len=3648

2. vxprint command:

Run vxprint -l <diskgroup> and again look for the version field as shown in the example.

# vxprint -l dg_sap

Disk group: dg_sap

Group:    dg_sap
info:     dgid=1273503890.14.serv1
version:  140 <--- version
alignment: 8192 (bytes)
activation: read-write
detach-policy: global
dg-fail-policy: dgdisable
copies:   nconfig=default nlog=default
devices:  max=32767 cur=1
