Replacing a disk drive in an F85

About disk drive failures

When a disk drive fails, the F85 logs the following disk drive failure identification message in the messages log and to the system console.

Fri Oct  9 15:58:08 GMT [rc]: Disk 0b.1 is broken

1 disk is broken.

Fri Oct  9 15:58:08 GMT [rc]: A disk is missing from one or more 
RAID groups.

In the preceding message, the failed disk drive is identified as 0b.1. The following table provides an explanation of this identification, which is the disk host address.

Note
See the Data ONTAP System Administrator's Guide for more information about the disk host address.

Disk host address	Explanation
4b	This is the host adapter number. The numeric value usually indicates the expansion slot number in which the SCSI adapter is installed.
1	This value indicates the SCSI ID number. The drives are identified as SCSI ID 0 through 5. In this example, the drive identified as SCSI ID 1 is the drive that must be replaced.

Removing a disk drive

To remove a disk drive, complete the following steps.

Note
Since the disk drives are hot-swappable, the F85 need not be shut down.

Step	Action
1	Wear the antistatic wrist strap and attach the grounding leash to the filer chassis.
2	Turn the keylock on the front bezel of the computer to the unlocked position.
3	Grasp the bezel along the edge adjacent to the filer chassis and unsnap the bezel to remove it from the filer chassis.
4	If your F85 is...	Then...
5	A tower system	Pivot the bezel downward until it is at a right angle to the filer chassis.
6	A rack-mount system	Pivot the bezel to the right until it is at a right angle to the filer chassis.
7	Wait until the drive status indicators adjacent to the drive bay signal that you can remove the drive safely. The drive status indicators flash sequentially as the drive is powered down. When all the drive's status indicators are turned off, the drive is ready for removal.
8	Open the drive carrier handle to release the carrier.
9	Slide the carrier toward you until it is free of the drive bay.
10	Remove the four screws that secure the disk drive to the carrier and remove the drive from the carrier. Set the screws aside for later use.

Installing a disk drive

To install a disk drive, complete the following steps.

Step	Action
1	Pull the new disk drive out of the antistatic bag and put the disk drive you are replacing into the same antistatic bag.
2	Insert the replacement disk drive into the carrier and secure it with the four screws you set aside.
3	Install the replacement disk drive and carrier into its slot.
4	Raise the handle until it engages the front panel, then close the latch to ensure that the disk drive is fully seated in the SCSI backplane board.
5	Snap the two tabs near the lower inside edge of the front bezel into the corresponding metal clips on the chassis, and
6	If your F85 is...	Then...
7	A tower system	Pivot the bezel upward into its closed position.
8	A rack-mount system	Pivot the bezel to the left into its closed position.
9	Turn the keylock on the front bezel of the computer to the locked position.
