    DiskGroup drops the disk immediately when test multipath recovery

    1026407

      Hi.

      I use SDDPCM.When I  test multipath recovery,the diskgroup drops the disk immediately.However, I set the DISK_REPAIR_TIME=3.6h.

      Host:IBM AIX 6100-08-02-1316

      Oracle:11.2.0.4

      Storage:IBM DS8700

      SDDPCM Version:2.6.3.2


      1.From the host level,every path and disk is fine.

      2.# pcmpath query device,only the hdisk9 is close and droped from the diskgroup immediately.It seems that the parameter 'DISK_REPAIR_TIME=3.6h' is not work.

      3.When I query the disks,hdisk9 is droped.

      ASMCMD> lsdsk

      Path

      /dev/rhdisk10

      /dev/rhdisk11

      /dev/rhdisk3

      /dev/rhdisk4

      /dev/rhdisk5

      /dev/rhdisk6

      /dev/rhdisk7

      /dev/rhdisk8

       

      I am rearlly confused by this situation.Thanks for your help!
