• Phy Count—Displays the number of phys for each physical drive. Single-ported drives have
one phy. Dual-ported drives have two phys.
• Multipath Status—Displays the overall multipath status of this physical drive. The following
values are valid:
◦ Not Configured—Indicates that the physical drive is not configured to have multipath
access.
◦ Redundant—Indicates that the physical drive currently has more than one I/O path to
the controller.
◦ Not Redundant—Indicates that the physical drive previously had more than one I/O path
to the controller but now has no redundant I/O path.
◦ Disk Failed—Indicates that the physical drive has failed.
Paths
For multipath-capable hardware, the status and role of each data path to the physical drive is
reported.
• Path—Indicates the path to the physical drive. Each path is identified by a descriptor, for
example "Port 2E Box 1 Bay 12" indicates a path from the host adapter external port number
2 ("Port 2E") to the 12th bay in the first box.
• Status—Indicates the status of the data path. Possible values are:
OK—The path is operational.◦
◦ Link down—The path is not operational.
◦ Unknown—The path status cannot be determined.
• Role—Indicates the role of this path in the configuration. Possible values are:
Active—This path is the preferred data path to the physical drive.◦
◦ Alternate—This path is the alternate data path to the physical drive.
◦ Unknown—The role of this path cannot be determined.
