Re: replacing mirror disk hard disk off-line procedure
since the A180 is the only a-class with non hotpluggable disks, you need to do this
- run "ioscan -fnCdisk"
to get your disk device files
- run "dd" against it
(e.g. "dd if=/dev/dsk/c0t5d0 of=/dev/null" - use your device files)
- if you get an IO error, take note of the scsi ID - in the example above it is 5)
- shutdown and open the box, take a look at the jumpers to find the right disk
Hope this helps!
Regards
Torsten.

Re: replacing mirror disk hard disk off-line procedure
# echo "boot_strings/S" | adb /dev/vmunix /dev/kmem
it will show you something like this..
boot_string:
boot_string: disk(0/0/1/1.15.0.0.0.0;0)/stand/vmunix
run lssf against c1t15d0 or c3t15d0 in your a class to verify which disk in the above said position. Replace it. Make sure your server can boot from alternate path and boot the secondary boot disk.
Once you login to the system, restore the appropriate vg information to the new replace disk.
# vgcfgrestore -n /dev/vg00 /dev/rdsk/c1t15d0
Activate vg00
# vgchange -a y vg00
Reinstate the boot device and LIF data
# mkboot -b /dev/rdsk/c1t15d0
Verify.
# lifls -l /dev/rdsk/c1t15d0
# mkboot -a "hpux -lq" /dev/rdsk/c1t15d0
# lvlnboot -vR /dev/vg00
Synchronized vg00. This make take a while...
# vgsync vg00
Once complete, check status by running lvdisplay to confirm there is no stale extents.
