24.7.9 Operation at the time of cancellation

24.7.9.1 Canceling the backup relationship

The sfcproxybreak(1M) command is used to cancel the backup source to backup destination relationship.

For details on sfcproxybreak(1M), see Appendix F.2.16, "sfcproxybreak(1M)."

The following example shows the specification for canceling a relationship named backup1_for_volume0001. Execute this command in nodes that share the backup source file system.

# sfcproxybreak backup1_for_volume0001

Next, if the backup destination file system is unnecessary, delete the file system with the sfcadm command.

24.7.9.2 Release of the volume locks

If a volume start lock is set for the backup destination volumes when a relationship is being set up, release that lock if necessary.

The GDS command sdxattr(1M) is used on each node to cancel the volume lock for that node.

For details on the sdxattr command, see "Command Reference" in the "PRIMECLUSTER Global Disk Services Configuration and Administration Guide."

(Example) Releasing the volume lock on the backup destination

The backup destination consists of the GDS volume /dev/sfdsk/class0001/rdsk/volume0001- (class class0001 and volume volume0001-) If a volume start lock is set in nodes nodeA and nodeB, the following command are executed in nodes nodeA and nodeB.

nodeA:
# sdxattr -V -c class0001 -v volume0001- -a lock=off
nodeB:
# sdxattr -V -c class0001 -v volume0001- -a lock=off
