Do you know if the drive was used on ( VAX, Alpha, PC ) ?
If it was used on a VAX, the problem is drive spin-up. When disk
drives spin-up they take a lot of current. This causes problems with
power supplies when many drives spin-up at one time. To solve this
problem, drives were set not to spin up on power up. They wait for a
SCSI spin up command. The O/S spins each drive in sequence. The RZ24L
has a EEPROM that holds the setting. If you have access to a VAX or
IBM compatible PC I have programs that can reprogram the drive to
spin up or just stop by the plant.
