5.4 Dismounting Drives

5.4Dismounting Drives

Since the method and procedure for dismounting the disk drive for replacement of the drive, etc. depends on the locker structure of the system, etc., the work procedure must be determined in consideration of the requirements specific to the system. This section describes the general procedure and notes on dismounting the drive.

Damage

1.When dismounting the drive which is mounted on the system while power is supplied to it.

The drive to be dismounted must be separated from the loop. Dismounting the drive which is not separated from the loop may cause an unexpected error.

If the drive is not separated from the loop, issue an LPB to the drive from the initiator in a primitive sequence of the order set.

It is recommended to stop the spindle motor prior to this loop separation operation. The spindle motor can be stopped by a START/STOP command. It takes about 30 seconds for the spindle motor to stop completely.

Then, dismount the drive using the drive mounting/dismounting mechanism, etc. of the system. If the drive is dismounted while the spindle motor is running, special care is required to avoid excessive vibration or shock to the drive. It is recommended to stop the operation once the SCA connector breaks off contact and wait until the spindle motor stops (about 30 seconds) before dismount the drive.

When storing or transporting the drive, put it in an antistatic bag. (Shown in Section 5.1).

2.When dismounting the drive which is mounted on the system while power is not supplied to it.

Do not move the drive until the drive stops completely (about 30 seconds if the spindle motor was stopped by a START/STOP UNIT command, and about 30 seconds after powering-off when the power was simply turned off).

Then, dismount the drive using the drive mounting/dismounting mechanism, etc. of the system.

When storing or transporting the drive, put it in an antistatic bag. (Shown in Section 5.1).
