Setting up Mirroring on root disk : system hangs

[Mahesh Ganga]

Hi,

I am trying to setup mirroring on my server with 2 internal drives. The OS(11i) is installed on one.

pvcreate and vgextend went ok but "makeboot /dev/dsk/c2t1d0" hangs the entire system. Did anyone see this problem ?

Hi,

I think mkboot works with /dev/rdsk. isn't it ?.

Hope this helps.

Sorry!
This is what I tried:
mkboot -l /dev/rdsk/c2t1d0
and it hangs.

Correct - rdsk:

mkboot -l /dev/rdsk/c3t6d0

I attached a procedure I ues.

Hi,

Try these two patches,

1.) PHCO_28378
2.) PHCO_27101

And here is the cookbook to create a root mirror,

http://www1.itrc.hp.com/service/cki/docDisplay.do?docLocale=en_US&docId=200000073345589

The itrc doc id is LVMKBRC00005103.

Make sure you are using the correct device file.

Hope this helps.

This is what I use and works ok..It's written for my collegues, so it contains a lot of explanations as to why something is done..
See file attached..

Thank you all for the help.

It looks like the disk is bad. We found out that even though 'ioscan' and 'diskinfo' showed good data, the "dd" command did the same thing to the system(the system hung)

$ dd if=/dev/rdsk/c2t1d0 of=/dev/null bs=1024k
