vxdg can be used to list information about shared disk groups. To display information for all disk groups, use the following command:

# vxdg list

Example output from this command is displayed here:

NAME       STATE              ID
group2     enabled,shared     774575420.1170.teal
group1     enabled,shared     774222028.1090.teal

Shared disk groups are designated with the flag shared.

To display information for shared disk groups only, use the following command:

# vxdg -s list

Example output from this command is as follows:

NAME     STATE            ID
group2   enabled,shared   774575420.1170.teal
group1   enabled,shared   774222028.1090.teal 

To display information about one specific disk group, use the following command:

# vxdg list diskgroup

The following is example output for the command vxdg list group1 on the master:

Group:     group1
dgid:      774222028.1090.teal
import-id: 32768.1749
flags:     shared
version:   140
alignment: 8192 (bytes)
ssb:       on
local-activation: exclusive-write
cluster-actv-modes: node0=ew node1=off
detach-policy: local
dg-fail-policy: leave
copies:    nconfig=2 nlog=2
config:    seqno=0.1976 permlen=1456 free=1448 templen=6 
loglen=220 
config disk sdk copy 1 len=1456 state=clean online
config disk sdk copy 1 len=1456 state=clean online
log disk sdk copy 1 len=220
log disk sdk copy 1 len=220

Note that the flags field is set to shared. The output for the same command when run on a slave is slightly different. The local-activation and cluster-actv-modes fields display the activation mode for this node and for each node in the cluster respectively. The detach-policy and dg-fail-policy fields indicate how the cluster behaves in the event of loss of connectivity to the disks, and to the configuration and log copies on the disks.
