APAR status

  • Closed as program error.

Error description

  • removing hdisks while using the AIX active / passive
pcm / DS 3, 5 and 5K may result in a hang in the PCM

Local fix

  • this is an unlikely timing event and may be resolved
by placing the hdisk in a defined state prior to
rmdev -Rdl the fscsi adapter pr pci bus

Problem summary

  • rmpath/rmdev command run on the active path of an AIX active/
passive disk(DS3K/DS4K/DS5K) may hang. All further IO to the
disk may hang.

Problem conclusion

  • It should be ensured by using a timer that the fail over
command is sent down even when there is no current IO on the
active path of the disk.

Temporary fix
