1. We see the following message in errpt

2. From oem_setup_env. You will see half of the paths are in a failed state:

# pcmpath query device

3. During parts replacement procedure from HMC you will receive a message that some devices are in use and need to be removed prior to FRU replacement. They will be the PCI slot and fc device. In this case they were fcs0 and pci8. Remove the slot recursively.

rmdev -Rdl pci8

This will actually delete it and all of the children devices from the ODM. Once this is done you can complete the FRU replacement.

4. You will run cfgmgr as part of the FRU replacement. You may recieve and error, don't worry about it. Now you have to update the SVC host config with the new WWN of the replaced HBA. Run the following to get it:

# lscfg -vl fcs0
fcs0 U7879.001.DQDKDNR-P1-C4-T1 FC Adapter

5. Update the host properties on the SVC. Run cfgmgr again. Then:

DEV#: 2 DEVICE NAME: hdisk2 TYPE: 2145 ALGORITHM: Load Balance

5* fscsi0/path1 OPEN NORMAL 8 0
6 fscsi0/path2 OPEN NORMAL 8 0

BINGO!! You are in business!! DRINK BEER!!

这里有个犯例，是VIO！！！

你试试……
