Disk names for direct-attached disks

Names for direct-attached disks (disks that are attached directly to the storage system rather than through a switch) are based on the host adapter or port number, followed by the disk ID, in the following format: portID.diskID.

portID refers to the host adapter or port number as follows:

Onboard expansion slots use the port number that is cabled to the disk shelf that contains the disk.
Host adapters use the expansion slot number on the storage system where the host adapter is attached, appended with the port number on the host adapter.

Note: Internal disks are considered to be connected via a specific onboard expansion slot. The slot number is platform-dependent. For the FAS2000 series systems, the slot number used for internal disks is 0c.

Examples

A disk with an ID of 33, connected via FC-AL to the B port of an adapter installed in expansion slot 4, would have the following name: 4b.33

A disk with an ID of 22, connected via FC-AL to onboard port 0a, would have the following name: 0a.22

An internal SAS-connected disk in a FAS2000 series system, occupying drive bay 17, with the internal disk shelf ID set to 0, would have the following name: 0c.0.17
