Hi all,

We are running 10.2.03 on Redhat 3.

We have ASM installed and are using EMC San for storage. We had a hardware panic and 3 (these were part of the failover group) of the 6 disks available went offline but reappeared as blank group name:

Code:
PATH                           NAME                           STATE
------------------------------ ------------------------------ --------
/dev/raw/raw6                                                 NORMAL
/dev/raw/raw5                                                 NORMAL
/dev/raw/raw4                                                 NORMAL
                               DGGROUP_0005                   FORCING
                               DGGROUP_0004                   FORCING
                               DGGROUP_0003                   FORCING
/dev/raw/raw3                  DGGROUP_0002                   NORMAL
/dev/raw/raw2                  DGGROUP_0001                   NORMAL
/dev/raw/raw1                  DGGROUP_0000                   NORMAL
As can from above, raw6,5,4 now appear with no name but are online, the blanks are all offline. I did a alter diskgroup check all and this did not throw up any errors. Now how do i get the raw6,5,4 to be part of a failover group?

Code:
SQL> select failgroup, name from v$asm_disk;

FAILGROUP                      NAME
------------------------------ ------------------------------



                               DGGROUP_0005
                               DGGROUP_0004
                               DGGROUP_0003
PRIMARY                        DGGROUP_0002
PRIMARY                        DGGROUP_0001
PRIMARY                        DGGROUP_0000
Also does this mean the even though these disks are not part of the failure group, normal redundancy is still availabe as all 6 are still online? Any help will be greatly appreciated

Thanks in advance
