Interpreting Drive Properties

Because some fields in this dialog require no explanation, the table below focuses only on those fields which require additional detail.

Field

Description

Channel/ ID

Displayed for SCSI drives. The SCSI channel number is listed first, then the SCSI ID.

Example: Channel 2/ ID 1

Port 1 Channel/ ID

Displayed for Fibre Channel drives.

Port 1: The drive port performs data communications over the fibre channel link. Fibre Channel drives have dual ports, for redundancy. Each port is connected to one of the channels. This data field is associated with the first drive port seen by the controller.

Channel: The Channel is the controller's drive interface channel number.

ID: The Loop ID (actual) of the drive is an ID for the drive unique to the drive port. Each port resides on one redundant drive loop. The preferred Loop ID, used to determine the Preferred AL_PA (hard address), might not be available on both loops, so the ID for the drive can vary from Drive Port 1 to Drive Port 2.

Example: Port 1 Channel 1/ID 2

Port 2 Channel/ ID

Displayed for Fibre Channel drives.

This is the channel and ID information for the second drive port seen by the controller. See the previous information for Port 1 Channel/ID.

Example: Port 2 Channel 2/ID 6

Raw Capacity

This is the full capacity of the drive, including any capacity that is reserved for storage subsystem management and control.

Example: 8.479 GB

Usable Capacity

This is the capacity of the drive after space reserved for storage subsystem management and control is allocated on the drive.

Example: 8.44 GB
