rx2660 failed disk swap query
Hello,
I had the failed hard drive yesterday and I replaced it with a new working one:-
disk 2 0/1/1/0.0.0.5.0 sdisk NO_HW DEVICE HP DG146BB976
/dev/dsk/c0t5d0 /dev/rdsk/c0t5d0
I then perormed the following commands to be able to see the new drive:-
rmsf -H 0/1/1/0.0.0.5.0
insf -e
ioscan -fnC disk
This worked fine but the new disk is being seen as the following:-
disk 18 0/1/1/0.0.0.8.0 sdisk CLAIMED DEVICE HP DG0146FARVU
/dev/dsk/c0t8d0 /dev/rdsk/c0t8d0
is there a way using sasmgr to rename the disk to what it was originally?
Cheers
Nick

Re: rx2660 failed disk swap query
To get the new disk to use the old c0t5d0 device file you'll need to do:
# sasmgr replace_tgt -D /dev/sasd0 -q old_tgt=/dev/dsk/c0t5d0 -q new_tgt_hwpath=0/1/1/0.0.0.8.0
This assumes that your SAS device is /dev/sasd0.

Re: rx2660 failed disk swap query
For exactly this reason I recommend to use hardware raid in thiese servers - its getting even worst with 11.31.
Hope this helps!

Torsten.

Re: rx2660 failed disk swap query
Hello,
I have just tried that and it failed with the following:-
sasmgr replace_tgt -D /dev/sasd1 -q old_tgt=/dev/dsk/c0t5d0 -q new_tgt_hwpath=0/1/1/0.0.0.8.0
ERROR: Invalid qualifier (old_tgt) was specified

Re: rx2660 failed disk swap query
Hello,
No reboot has been done as I thought these were hot swap disks?
I've actually done this before on a rx6600 as I have just checked through some notes and I used the following syntax:-
sasmgr replace_tgt -D /dev/sasd0 -q old_dev=/dev/dsk/c2t2d0 -q new_tgt_hwpath=0/4/1/0.0.0.8.0

Re: rx2660 failed disk swap query
Try that. I may have made a typo or misread things when posting the command I did.

Re: rx2660 failed disk swap query
I think I know whats going on, I removed the missing device using the following command:-
rmsf -H 0/1/1/0.0.0.5.0
so c0t5d0 does not exist anymore hence me not being able to run the sasmgr replace_tgt command, does this make sense?

Re: rx2660 failed disk swap query
Yes. Same after a reboot, thats why I asked.
So you need to remove the missing disk from the vg (vgreduce -f) and start over with mirroring.
Hope this helps!

Torsten.
