A fix is available
APAR status
Closed as program error.
Error description
While in use and actively reading / writing to luns, the target controller is rebooted. After the controller rejoins the san fabric, it's target function has not completely initialized and when AIX initiates a login to that target port, the target now reports it is not target capable. The FC driver will never attempt a re-login even if prompted by an RSCN or fabric event.
Local fix
rmdev -Rl fcs may force a re-check of the target
Problem summary
After a storage box reboot, IO to all luns under one or more target ports may fail. In trace, it may be seen that IO fails with EIO and details may show adapter error as "No Device Response".
Problem conclusion
The driver code modified so that initially if target port does not exhibit "Target Function", then there will be RELOGIN attempts.
Temporary fix
