If you cannot find the SRN
, refer to the
documentation for the subsystem or device. If you still cannot find the SRN, you
have a problem with the diagnostics, the microcode, or the documentation. Call
your support center for assistance.
2. Read carefully the “Action” you must do for the problem.
Do not exchange
adapters unless you are instructed to do so
.
3. Normally exchange only one adapter at a time. Always use instructions provided
