Releasing a disk set is useful when you perform maintenance on the physical disks in the disk set. When a disk set is released, it cannot be accessed by the host. If both hosts in a disk set release the set, neither host in the disk set can access volumes or hot spare pools defined in the set directly, although if both hosts release the set, the hosts can access the disks directly through their c*t*d* names.
This option is not available for multi-owner disk sets.
Use one of the following methods to release a disk set.
From the Enhanced Storage tool within the Solaris Management Console, open the Disk Sets node. Right-click the Disk Set you want to release, then choose Release Ownership from the menu. For more information, see the online help.
metaset -s diskset-name -r
Specifies the name of a disk set on which the metaset command will work.
Releases ownership of a disk set. The reservation of all the disks within the disk set is removed. The volumes within the disk set are no longer accessible.
See the metaset(1M) man page for more information.
Disk set ownership is only shown on the owning host.
Verify that the disk set has been released on this host by using the metaset command without any options.
lexicon# metaset -s blue -r lexicon# metaset -s blue Set name = blue, Set number = 1 Host Owner lexicon idiom Drive Dbase c1t6d0 Yes c2t6d0 Yes
This example shows the release of the disk set blue. Note that there is no owner of the disk set. Viewing status from host lexicon could be misleading. A host can only determine if it does or does not own a disk set. For example, if host idiom were to reserve the disk set, it would not appear so from host lexicon. Only host idiom would be able to determine the reservation in this case.
