Hi Fellow-Admins,
thanks very much to all of you ,
especially to
Dr. Tom Blinn, Whitney Lotta,Davis Allan
and Phil Baldwin
for providing help so quickly.
It was mostly advised to use #dsfmgr -e dsk7 dsk2 respectively #dsfmgr -m
dsk7 dsk2.
But in my case the system refused to accept this command, telling me that
the (replaced)
dsk2 is busy, although this drive wasn't there anymore and being replaced by
a new
disk, that now shows up under dsk7.
Phil Baldwins hint finally solved the problem. Basically, it was necessary
to delete
the old disk device-entry in the device database first. After doing that,
the dsfmgr -m
command worked as expected.
Here the complete procedure:
Assumption: dsk2 failed and was replaced by a new disk in the same physical
storagewoks-slot.
1.) Note the HWID of the failed drive.
2.) Take out the defektive disk and replace it with the new one.
3.) find the new disk: #hwmgr scan scsi
#hwmgr show scsi
The new installed disk (in my case) now shows up as dsk7, and the old
removed
Disk shows devicefile null and no valid path.
4.) Check new disk entry in device database
grep "dsk 7" /etc/dfsc.dat (Note HWID)
5.) Check old entry from the disk being removed
grep "dsk 2" /etc/dfsc.dat (Note HWID) HWID must be the same as in
step 1
6.) Check that the old disk is now unknown to the system:
#hwmgr -show comp -id 48 <--HWID entry from removed disk2
7.)If there is NO OUTPUT continue with step 8, otherwise call Sys.Support.
8) Delete old disk-entry from both, local-and cluster devicedatabase.
#dsfmgr -Z rm_cluster_hwid 48 <--HWID entry from removed disk
#dsfmgr -Z rm_local_hwid 48
9.) hwmgr scan scsi
10.)assign name dsk2 to dsk7:
#dsfmgr -V -m dsk7 dsk2
That's it.
Here my original question:
