Remove Sun Cluster Settings
If you are using Sun Cluster, before you remove HDLM, perform the following
to remove the disk device group settings and the Quorum device settings.
If you are using SDS or SVM, delete the disk device group to which the
disksets that use HDLM belong to unregister them. If you are using SDS, see
Remove SDS Settings on page 3-183 of Preparations for HDLM Removal on
page 3-179 . If you are using SVM, see Remove SVM Settings on page 3-184
of Preparations for HDLM Removal on page 3-179 . Unregistering a diskset
deletes data in the diskset. Make sure that you first back up the data. If you
are using VxVM, delete the disk device group, delete the disk device group
that contains the disk group that uses HDLM to unregister the disk group.
The following procedure shows how to unregister a disk group.
To unregister a disk group:
1
.
Place the disk device group offline.
# /usr/cluster/bin/scswitch -F -D disk-device-group-name
2
.
Start the scsetup utility.
# /usr/cluster/bin/scsetup
3
.
Enter 5 (Device group and volumes) to work with VxVM disk device
groups.
