【AIX】ファイバーアダプターが壊れたよ

ファイバーアダプター交換手順のメモです。

Depends on what version of SDD you are running...

if you have the option
datapath remove adapter
then yes it can be done online. If not, then you need a downtime...

step 0 - identify your faulty adapter name
lsdev -Ccadapter | grep fcs

step 1 - identify your faulty adapter number in SSD config
datapath query adapter

step 2 - remove adapter from SDD config
datapath remove adapter N
(use number from step 1 instead of N)

step 3 - remove adapter from ODM
rmdev -Rdl /dev/fcsM
(use number from step 0 instead of M)

step 4 - use diag/PCI hot plug tasks to replace the adapter - probably your CE will do this.

step 5 - identify your new WWNN and adapt your storage server to assign the LUNS to the new WWNN
lscfg -vl fcsM

step 6 - run cfgmgr to rediscover the deleted paths to your LUNs
cfgmgr -vl fscsiM

step 7 - add paths to SDD
addpaths

step 8 verify all LUNS have same number of active paths
datapath query device
datapath query adapter
