318 HP StorageWorks Disk Array XP RAID Manager: User’s Guide
The RM configuration files show one RM group defined. The group,
Group1
, contains two disks. The comments note that system blue is
defining the P-VOLs and system yellow is defining the S-VOLs. However,
the P-VOL/S-VOL relationship is set when the paircreate command is
issued. The set of disks that becomes the P-VOL or S-VOL depends on two
conditions:
• the RM instance to which the command is issued
• the option specified in the paircreate command
The instance that the command is issued to becomes the local instance. If
the option passed to the paircreate command is –vl, then the volumes
defined in the local instance become the P-VOLs. If the option is –vr, the
volumes defined in the remote instance become the P-VOLs.
