IJ05435: IF UNUSED, LUN ID 0 COULD BE INACCESSIBLE ON SOME STORAGE ARRAYSAPPLIES TO AIX 6100-09

 

APAR status

  • Closed as program error.

Error description

  • Lun id 0 could be left inaccessible on some storage
arrays
if rootvg had not been installed on lun id 0. This is
related to the scsi reports luns response from the array
where lun id 0 is expected to be the first lun which for
some arrays it may be the 2nd or 3rd etc.

If lun id 0 is not the first lun returned in the lun list
scsidisk config method will inadvertently keep
lun id 0 sciolstarted which results in not being able to
access lun id 0 after system boot.

Local fix

  • 



Problem summary


    

  • In SAN environment, if the hdisk's lun id is zero, then, the
disk could be inaccessible

    



Problem conclusion


    

  • Code is modified to go through the report lun list. If, any
lun has its id as zero, then, the particular lun is replaced
as the head of the list

    



Temporary fix
