Removing the SAN Volume Controller 2145-4F2 disk drive
Attention:
v Handle the disk drive with care and keep it away from strong magnetic fields.
v The disk drive is electrostatic-discharge (ESD) sensitive. Take precautions to avoid damage from static
electricity. Wear an anti-static wrist strap and use a static-protected mat or surface. For more
information, see “Handling static-sensitive devices” on page xix.
To remove the disk drive and cables, perform the following steps:
1. Verify that all operations between the node and the host system have been stopped.
2. Turn off the node while ensuring that its data is mirrored and synchronized. See MAP 5350 in the
IBM System Storage SAN Volume Controller 2145 Troubleshooting Guide for more information.
3. Remove the node from the rack and place it on a flat, static-protective surface. See “Removing the
SAN Volume Controller from a rack” on page 40.
