11Disk Defect List Screen | APC 15000 RAID manual

Figure 3–11Disk Defect List Screen

DISK FAIL=<tier><channel> instructs the system to fail the specified disk at the physical tier in the range of <1 ...125> and channel in the range of <ABCDEFGHPS>. When a non-SPARE disk is specified and it is failing, the disk will not cause a multi-channel failure. The disk is marked as failed. An attempt is made to replace it with a spare disk. When a SPARE disk is specified and it is currently in use as a replacement for a failed disk, the disk that the spare is replacing is put back to a failed status and the spare is released, but marked as unhealthy and unavailable.

DISK PLS=<tier><channel> requests/displays the PHY Link Error Status Block information for the specified drive.

The disk is specified by its physical tier and channel locations, 'tc', where:

•'t' indicates the tier in the range <1..120>, and

•'c' indicates the channel in the range <ABCDEFGHPS>.

If neither the tier nor the channel are specified, the PLS information is requested from all drives. If only the tier is specified, the PLS information is requested from all the drives on the specified tier.

Table 3–2 on page 37 shows the types of PHY errors. Note that SATA and SAS drives report PHY errors differently.
