Disk Attribute Descriptions

If you configure a disk volume for use with an FCSA connected to an ESS, you

cannot specify BACKUPDEVICEID.

BACKUPLOCATION ( group, module, slot )

(45xx and M8xxx disks only) is the location of the adapter that controls the

backup path to the device.

This attribute is optional if BACKUPSAC is given in name format but required if

BACKUPSAC is given in number format.

BACKUPPORTNAME number

specifies the Fibre Channel port name (WWN) used by the backup path to a disk

volume on the Enterprise Storage System (ESS).

The ESS administrator must give you the WWN so that you can specify it in this

attribute.

Enter number as a 16 character hexadecimal number, without a leading %H.

BACKUPSAC { number | name }

is the SAC that controls the backup path to the device.

Note. This attribute is not valid for the PROFILE object.

number is the SAC subdevice number on the adapter.

If you specify BACKUPSAC in number format, you must also

specify BACKUPLOCATION.

name is the full name of the SAC location. For example:

SNDA.SAC-1.GRP-1.MOD-1.SLOT-53

FCSA.SAC-1.GRP-11.MOD-2.SLOT-5

Use this form to override the default selection of which adapter gets

the -P path and which gets the -B path.

An FCSA must be located in either MOD- 2 or MOD-3 of an IOAM

enclosure. There are five slots in each IOAM module
