Note

After registering the VxVM disk group into a Sun Cluster disk device group,

do not use the VxVM command to import or deport that VxVM disk group.
If you register the VxVM disk group into a Sun Cluster disk device group

where more than 3 nodes are configured, the following message might

appear when changing the node that acts as the master for the disk group. If

this message appears, ignore it.

KAPL05023-E Could not process the IOCTL(00004D03).

(0000000D:00000000)

If the VxVM volume has not been created, create a VxVM volume in the disk

group from the master node (the node that currently acts as the master for the disk

device group). The following shows an example of executing the command:

# vxassist -g dlmdg make vol-dg 10g

To create a volume or otherwise modify the VxVM disk group after it has been

registered into a Sun Cluster disk device group, execute the

scsetup

utility to

register the change in the VxVM disk group configuration into Sun Cluster.
This ensures that the Sun Cluster global device namespace status is correct.
For details, refer to the explanation of system administration in the Sun Cluster

documentation.
The following shows the procedure:

• Start the

scsetup

utility.

# /usr/cluster/bin/scsetup

The

Main Menu

appears.

• Enter 5 (Device group and volumes) to perform operations on the VxVM

disk device group.

• Enter 2 (Synchronize volume information for a VxVM device group) to

configuration was changed.

If the file system has not been created, execute the

newfs

command to create the

file system.
The following shows an example of executing the command:

# newfs /dev/vx/rdsk/dlmdg/vol-dg
