- Help!!! I need help getting our RS6k back up. IBM has been no help
- so far, thus I was hoping the net would fill in what IBM can't. Here's
- my story:
-
- Last night we powered down our rs6000 to do a little disk moving. We
- have 2 SCSI channels and wanted to split our disks across them. Before
- I did anything else, I did a mksysb backup (thru smit). After the backup
- I exported the vg (chemvg) which was a 2 disk vg. I was going to split
- this VG across both SCSI channels and thought this would be safest. Well
- I guess I was wrong because we are now stuck.
-
- To continue, after exporting the VG we shutdown. I then moved one of the
- SCSI disks on scsi0 to scsi1. I also added a new disk to scsi1. This left
- a configuration of scsi0: rootvg (hdisk0), uservg (hdisk1), chemvg (hdisk2)
- scsi1: chemvg (hdisk3), scratchvg (hdisk4), ??? (hdisk5)
- Or at least this is what I expected when I rebooted. Well, it wouldn't
- reboot! I finally had to go into MAINT mode where I executed 'getrootfs'
- It returned a list of hdisks it new about, saying that hdisk3 was bootable.
- Now this should have been hdisk0!
-
- After further examination we discovered that scsi0 was now scsi1 and vise
- versa. We have tried many things from booting the mksysb we made and
- restoring rootvg to clear nvram (which we are now running diags on).
- We have also done 'getrootfs hdisk3' and tried working with the files
- on the rootvg. getrootfs never does complete properly, but it acts the
- same whether we boot from our mksysb or the v3.2.2 install tape.
-
- I would like to point out that we were getting a flashing 517 as the stop
- point just before we cleared nvram and tried rebooting, thus receiving
- the stuck 552. For the life of me I can't understand why it wants to
- boot from the network. But that is now gone.
-
- I remeber hearing something a while back about a script out of defect
- support that allowed one to prune the ODM. I would like to find it so
- I can basically redefine my disks (which according to one of my manuals--
- General Concepts and Procedures??-- that the hdisk number should never
- change no matter where the disk is moved on the system as long as it has
- a PV Id# that is unique or is bootable. WHat gives?
-
- Sorry for the long message, but I am very frustrated. I have been here all
- night, and when my boss and I tried to get help out of Austin they sent us
- to our SE. What a joke. Our SE left 5monthes ago. He was replaced by a nice
- lady who is an SE but in the mainframe area. SHe has admitted tyhat she
- doesn't know AIX, which means we need help. One local guy did call us back
- on his vacation but he suggested a restore and then the ODM prune script,
- that is if I can get it out of AUSTIN!
-
- Any help will be much appriciated.
