High Availability Cluster/iX

SXOMAKELABEL

The SXOMAKELABEL command is used to create the cluster data structure, which include “Ownership label,”

associated audit trail information and history records. “Ownership Label” consists of the unique HPSUSAN

number of the system and the Root UFID of the System Volume Set. This command will set the “Ownership

Label” to that of the computer where the command was issued. The “Ownership Label” is assigned only to the

MASTER volume of the volume set created and not the member volumes.

Creation of “Ownership Label” prevents two systems from trying to mount the same volume set

simultaneously. Thus, disk operations are allowed only on disk volumes owned by the system.

NOTE The operator is responsible for verifying that this computer is the only one that has access to

the volume set until after the volume set has been created and the data structures built using

this command. After these structures are built, the system administrator can then configure

ldevs on the other computers that will be in the cluster configuration.
