When doing a vgextend I got this error message...
First doing a successfull pvcreate:
# pvcreate -B /dev/rdsk/c2t0d0
Physical volume "/dev/rdsk/c2t0d0" has been successfully created.
Then problems:
# vgextend /dev/vg00 /dev/dsk/c2t0d0
Volume group "/dev/vg00" has been successfully extended.
Unable to query the I/O interface: I/O tree node does not exist.
Volume Group configuration for /dev/vg00 has been saved in /etc/lvmconf/vg00.conf
# ioscan -fnk |grep disk
disk 0 0/0/2/0.0.0.0 sdisk CLAIMED DEVICE TEAC DV-28E-N
disk 2 0/1/1/0.1.0 sdisk CLAIMED DEVICE HP 73.4GMAX3073NC
The device (c2t0d0) I am looking for is missing...
disk 1 0/1/1/0.0.0 sdisk CLAIMED DEVICE HP 73.4GMAX3073NC
Any idea what could be wrong?
Best regards

Re: I/O tree node does not exist
# ioscan -f /dev/dsk/c2t0d0
# lssf /dev/dsk/c2t0d0
# lvlnboot -v
Are you trying to create vg00 for the first time or are you modifying it ex. replacing a small disk with a big one? Could you specify what you are doing on vg00.
~cheers

Re: I/O tree node does not exist
For the first time I'am trying to configure a MirrorDisk/UX setup. Mirroring all logical volumes at vg00. It's all working find for two disks. I have tested to removed one disk at the time and both are booting fine from each of them. Everything ok.
When I want to replace one of the disks with a new one, I start getting these problems...

Re: I/O tree node does not exist
vgreduce seems to fix the problem.
Mirroring working fine and I am able to boot from the disk also :-)
Thank you both for helping me!
