5–10 SF3x Storage Enclosure FRU Replacement
5.1.2 Warm Swap and Repair Procedures
Before you start the removal and replacement procedures, you must
obtain all necessary parameters from the device to be replaced, or
operating system data structures. If you have not done this, refer back to
Section 5.1.1.
Check that the parameters you obtained from the preceding steps are
accurately recorded on the DSSI Configuration Sheet for this unit.
Configuration sheets should be in the Site Management Guide . Make
any necessary corrections to the recorded information.
To remove the disk ISE from the storage enclosure:
1. At the system console, dismount the faulty disk ISE through the VMS
operating system. For example:
>> DISMOUNT $1$DIA21
2. Take the disk ISE off-line by pressing Ready on the operator control
panel (OCP) for the disk ISE being removed (Figure 5–1).
3. At the bottom front of the storage enclosure, set the drive dc power
switch to off (Figure 5–1). The switch LED should go out to indicate
that power has been removed from the disk ISEs. If the LED does not
go out, suspect a faulty switch.
CAUTION
Do not attempt the following steps unless you have taken
precautions against electrostatic discharge (ESD). Wear an
ESD grounding strap. Do not place the disk ISE on anything
other than a grounded antistatic work surface. Failure to
observe these precautions can result in ESD damage to the
disk ISEs.
4. Remove cover by removing two screws
5. Remove the disk ISE from the SF3x enclosure.
a. Remove the screw from the ISE carrier lever.
b. Pull the lever forward and slide the carrier out of the slot.
