SCSI Hard-Disk Drive Indicator Patterns

The three light-emitting diode (LED) indicators adjacent to each of the six SCSI hard-disk drive bays provide information on the status of the SCSI hard-disk drives. The SCSI backplane firmware controls the drive online and drive fault indicators, whereas the drive access indi- cator is usually controlled by the drive itself.

Table 10-1 lists the various drive indicator patterns. Dif- ferent patterns are displayed as drive events occur. For example, in the event of a hard-disk drive failure, the “drive failed” pattern appears. After the drive is selected for removal, the “drive being prepared for removal” pat- tern appears, followed by the “drive ready for removal” pattern. After the replacement drive is installed, the “drive being prepared for operation” pattern appears, then the “drive online” pattern.

Removing a SCSI Hard-Disk Drive With the System Running

Remove a SCSI hard-disk drive as follows:

1.Wait until the drive status indicators adjacent to the drive bay signal that the drive may be removed safely.

If the drive has been online, the three drive indica- tors will flash sequentially as the drive is powered down. When all three indicators are turned off, the drive is ready for removal.

2.Remove the hard-disk drive.

Follow the instructions in “Removing a SCSI Hard- Disk Drive,” found earlier in this chapter.

Inserting a SCSI Hard-Disk Drive With the

System Running

Insert a SCSI hard-disk drive as follows:

1.Remove the drive or empty carrier from the drive bay as described in the previous subsection.

2.Insert the “new” drive carrier into the bay.

Follow the instructions in “Installing a SCSI Hard- Disk Drive” found earlier in this chapter.

The drive online indicator turns on.
