APAR status

  • Closed as program error.

Error description

  • DS4000 disks which were previously managed by the
fcparray/RDAC driver now show up as "MPIO Other DS4K
Array Disk".  This is observed after installing one of
the following updates:
  VIOS 2.1 Fixpack 22/22.1
  VIOS 1.5 Fixpack 11.1 SP2
  AIX 6.1 TL04 base
  AIX 6.1 TL03 SP3
  AIX 5.3 TL11 base

This occurs if SDD PCM is also installed on the system,
but not managing the DS4000 storage.

This may also cause disk access errors if the system is
in a clustered environment, as the reserve_policy
attribute is changed back to the default of
"single_path".

Local fix

  • Use the "manage_disk_drivers" command to switch back to
the fcparray driver.

Problem summary

  • 53 disks coming up as MPIO instead of fcparray.

Problem conclusion

  • The scripts look for model_name after the new odm has been
installed. model_name does not exist in the new odm. That test
will be remmoved.

Temporary fix

  •
