Dismounting 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 case
(Fcell). (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 case
(Fcell). (Shown in Section 5.1).
