DescriptionType

Model M8xxx disks that reside in slots 1 through 14 of a Fibre Channel disk module (FCDM)

connected to FCSAs in an IOAM enclosure.

M8xxx

Disks within an Enterprise Storage System.ESS

Disks that attach to the system through CLIMs, such as Serial Attached SCSI (SAS) disk drives in

a SAS disk enclosure.

Configuring Paths for Different Disk Types

The values you specify when configuring a disk vary depending on the type of disk and the NonStop

server model. For example, the valid ranges for group, module, and slot of an M8xxx disk on an

Integrity NonStop NS-series server differ from those of an internal disk on a NonStop S-series server

Table 9 lists the possible attribute values for the different disk types.

Disks

* For Internal SCSI disks, SAC and DEVICEID are not required. SCF derives these values from the slot.LOCATION

represents PRIMARYLOCATION, BACKUPLOCATION, MIRRORLOCATION, and MBACKUPLOCATION.

SAC represents PRIMARYSAC, BACKUPSAC, MIRRORSAC, and MBACKUPSAC.

DEVICEID represents PRIMARYDEVICEID, BACKUPDEVICEID, MIRRORDEVICEID, and MBACKUPDEVICEID.

PORTNAME represents PRIMARYPORTNAME, BACKUPPORTNAME, MIRRORPORTNAME, and MBACKUPPORTNAME.

LUN represents PRIMARYLUN and MIRRORLUN.

For a CLIM-attached disk, tape, or Open SCSI device, path attributes are the CLIM name and the LUN.

Considerations for M8xxx Fibre Channel Disks

• In an FCDM containing M8xxx disks, at least one disk must be added for the enclosure to

be recognized by the storage subsystem.

• Before you add the first M8xxx disk in an enclosure to the storage subsystem, the primary

and backup paths must be physically connected.

• Before you add a mirrored pair of M8xxx disks to the storage subsystem, both paths to the

primary disk and the mirror disk must be physically connected.
