SCF Reference Manual for the Storage Subsystem (G06.28+, H06.05+, J06.03+)

For 45xx, ESS, and M8xxx disks, is the location of the adapter that controls the mirror path
to the disk.
This attribute is optional if MIRRORSAC is given in name format but required if given in number
format.
MIRRORLOCATION can be altered when all paths to the volume are in the STOPPED state.
MIRRORLOCATION can also be altered when all configured paths to the primary drive are in
STARTED state and MIRRORLOCATION is not yet configured. The result of an online
reconfiguration must be symmetrical. If the volume has a BACKUP path, it must also have a
MBACKUP path.
You cannot change the value of this attribute by using the ALTER command online after setting
it (using either the ADD or ALTER command). To change the value online, you must delete,
respecify the mirror location.
MIRRORLUN number
specifies the logical unit number (LUN) on the Enterprise Storage System.
NOTE: This attribute is not valid for the PROFILE object.
The ESS administrator must give you the LUN so that you can specify it in this attribute.
The default value for MIRRORLUN is 0.
MIRRORPORTNAME number
specifies the Fibre Channel port name (WWN) used by the path to a mirror disk volume on
an Enterprise Storage System (ESS)
NOTE: This attribute is not valid for the PROFILE object.
The ESS administrator must give you the WWN so to specify it in this attribute.
Enter number as a 16 character hexadecimal number, without a leading %H.
MIRRORSAC { number | name }
(mirrored 45xx and M8xxx disks only) is the SAC that controls the mirror path to the disk
NOTE: This attribute is not valid for the PROFILE object.
Is the SAC subdevice number on the adapter.number
Is the full name of the SAC location including the SAC number. For
example:SNDA.SAC-1.GRP-1.MOD-1.SLOT-53FCSA.SAC-1.GRP-11.MOD-2.SLOT-5
name
MODE { NOISY | QUIET }
specifies whether to generate additional EMS messages for debugging
NOTE: This attribute is only valid for virtual disks.
Generate additional EMS messages for debugging.NOISY
Generate only essential EMS messages (default).QUIET
NAMEMASK { STANDARD | name }
specifies a naming convention for automatically configuring disks
NOTE: This attribute is only valid for the PROFILE object.
The disk is named using the standard manufacturing naming convention (default). The name format
is $Dggss, where gg is the group number and ss is the slot number. For example, a disk inserted
