Action
Unseat the Drive Carrier card and reinstall
it. If the Drive Carrier card does not recover,
continue with this procedure.
Test the card by entering
LD 137
STAT CMDU
TEST CMDU
If the problem continues, a CIOD system
message appears. If the fault remains, replace
the Drive Carrier card.
If you have another CD, insert it into a known
operational Drive Carrier card, and load the
Software Installation Tool from the correct Install
Program diskette.
In the Software Installation Tool, go to the Tools
Menu and select
<j> -To check the customer-specific
part of the CD-ROM
If the test suceeds, it is unlikely the CD is
damaged.
However, if the test indicates a failure to read all
files on the CD, the CD is damaged and must
be replaced.
Remove the CD from the CD-ROM drive, place
it in the CD-ROM drive of the other Call Server,
and test operation.
If the CD is operational, replace the Drive
Carrier card that contains the faulty CD-ROM
drive.
