Listing shared disk groups

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

rootdg enabled 774215886.1025.teal

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

private_region_failure: leave

copies: nconfig=2 nlog=2

config: seqno=0.1976 permlen=1456 free=1448 templen=6 loglen=220

config disk hdisk12 copy 1 len=1456 state=clean online

config disk hdisk12 copy 1 len=1456 state=clean online

log disk hdisk12 copy 1 len=220

log disk hdisk12 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 private_region_failure 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.
