with I/O activity to the disk. If you observe different results, refer to chapter
4, Troubleshooting, for probable causes and solutions.
7 Run IOSCAN on the host and verify that the replacement disk module is
“claimed.”
8 Restore file systems and data as needed (see Preparation on page 111).
LCC
Replace an LCC when troubleshooting shows that the card is faulty (see
“Isolating Causes” in chapter 4).
There is no need to turn off the disk system to remove and replace an LCC.
However, the host must be notified that all disks on the affected loop will be
unavailable for I/O. Refer to Preparation on page 111.
Caution Touching the LCC pins can cause high energy discharge and
permanently damage the LCC.
Tools
■
ESD wrist strap (no hand tools are required to perform this procedure).
Whenever possible, follow ESD procedures.
Procedure
Caution Do not remove a LCC from an operating product until you have
the replacement LCC and are ready to install it. An empty slot will
cause uneven cooling and eventual overheating.
1 Remove the cables and/or terminators from the failed LCC.
2 Loosen the locking thumbscrew (A in Figure 58) until it clears the LCC
bulkhead. The screw stays in the ejector handle.
