7.

If HDLM devices are being used in Solaris 10 ZFS, execute the following

command to export all ZFS storage pools that are using HDLM:


# zpool export

pool-name

8.

Edit the

/etc/vfstab

file.

In the

/etc/vfstab

file, delete or comment out the specifications of the logical

device files for the HDLM devices (

Y

s

Z) and the ZFS file system whose

configurations you want to change, and then release the setting for automatic

mounting.

9.

Unregister HDLM-managed devices from the volume management software.
If any HDLM-managed devices are registered in the volume management

software, unregister them.

(2) Remove Sun Cluster Settings

If you are using Sun Cluster, before you uninstall 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 (5) Remove SDS

Settings of 3.17.2 Preparations for HDLM Uninstallation. If you are using SVM, see

(6) Remove SVM Settings of 3.17.2 Preparations for HDLM Uninstallation.

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

(Device group and volumes) to work with VxVM disk device groups.

Device Group Menu

is displayed.
