IBM RS/6000 SP manual Running diagnostics on a switch port

To complete the microcode update, it is usually necessary to remove and then replace the device from the configuration. The most reliable method to do this is to reboot the node. Some adapters can actually require a power off cycle to complete the microcode update. Others can be updated simply by running cfgmgr.

Note: During microcode download for SSA adapters, there is a possibility that the download process could result in an error. When an unrecoverable error (loss of power) occurs during the download process the adapter can be left with no microcode. If this happens, repeat the microcode download. If unsuccessful, replace the adapter.

7133 Disks can also be updated, however the method varies, depending upon which disks are attached. If

they are 4.5 GB or 9.1 GB ″Scorpion″ disks, and the AIX version is either 4.1.5 or 4.2.1, then run dsh "ssadload -u"to update the disks. Other disks will be updated by a cfgmgr or reboot cycle.

Running diagnostics on a switch port

Before running diagnostic tests on a switch to diagnose node to switch problems, you must identify the port number. For example:

Bulkhead jack 6 on switch 17 frame 1 is identified as E01-S17-BH-J6

To run the test from the control workstation for this example the syntax of the command is:

/usr/lpp/ssp/bin/spd/wrap_test -j E01-S17-BH-J6
