I decided to destroy one of my volume groups (it was used for testing) where we had the multiple disk failures to address rootvg being stale..
I found this article and followed it to fix my (rootvg.
Here are the events..

Now I did see something strange.. I have not yet phisically removed the failed disk (hdisk14) so when I run cfgmgr it gets picked up..
Code:
# lsdev -Cc disk | grep "hdisk14"
hdisk14 Available 03-08-01-5,0 16 Bit LVD SCSI Disk Drive
# lspv | grep "hdisk14"
hdisk14 none None
In turn, if I now run "bootlist -m normal -o" I get..
Code:
hdisk10 blv=hd5 pathid=0
hdisk14 pathid=0
Why is it showing there? I am concerned if a reboot happens I may not be able to boot.. how can I remove it and assign hdisk20 which is the replacement for hdisk14 in rootvg... or do I need to do anything further at this point?
Maybe just rmdev -l hdisk14 -d and leave it?

This may sound like an absolute rookie question, and it is.
I have been working on Migrating our HP and Solaris servers to the new EMC SAN and know the routines backwards.
Now we've suddenly got a new IBM server and I don't even know how to check if it is connected to the switch.
Can someone... (1 Reply)
We run two p5 nodes running AIX 5L in a cluster mode (HACMP), both the nodes share external disk arrays. Only the primary node can access the shared disks at a given point of time.
We are in the process of adding two new disks to the disk arrays so as to make them available to the existing... (3 Replies)
