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
