I am working on a system that has been shut down for a while, maybe weeks. When I boot the system the LUNs don't seem to be there. If I do a armdsp /dev/dsk/c4t0d0 I get the message "Device not Ready"
The VA7410 is powered up, any ideas on how to get the HP server to see it again?
HP rp5470 - HP-UX 11.11 Version 1
Any help would be greatly appreciated!
Tim

Re: VA7410 device not ready
I also have a warning stating that the batteries that backup the NVRAM in the array controllers have been depleted to the point where removing power from the controller may cause data loss.
Is this bad?
I looked in the cvui under diagnostics and there is a rebuild function. I am looking for a little guidance on where to go from here.
Rebuilding the entire array would be bad. Evidently there is archived data on this array and it needs to be available.

Re: VA7410 device not ready
I checked out these two links and the first one had some trouble shooting help but I didn't find any thing that would tell me how to rebuild the LUNs or if the disks not being included meant anything.
The second link doesn't seem to go any where, I could be doing something wrong.

Re: VA7410 device not ready
vfpdsp -s (to check the status)
vfpdsp -c (to check the controller)
vfpdsp -d (to check the disks)
vfpdsp -e (to check the enclosure)
vfpdsp -L (to check the luns)

Re: VA7410 device not ready
The cvui interface actually runs these commands from it's menu. So I am getting plenty of out put from the array. I can look at anything I want to.
Every thing seems to look good except when I look at the disks and none of them show include and non of my LUN's are showing any more.
The output of the #armdsp -a

Re: VA7410 device not ready
armdsp -a
will work too.
Try it again.
Better to know the current status before running any "diag" function.
The "rebuild" option will not help you at the moment, I guess.
Hope this helps!

Torsten.

Re: VA7410 device not ready
This is the odd part. cvui works just fine unless I try to look at the LUN status armdsp -L va7400 and it comes back with the following.
Status: Array Status
Device is not ready
The armdsp -a va7400 returns the same message. I am pretty sure that the batteries on the controllers NVRAM went dead while it was powered off. The only warning light that is on is for the battery
I did start another thread looking for information on the cvui utility. i was wondering what the "Rebuild" does or what the "Recover when NVRAM contents are lost" functions do. Maybe I am heading in the wrong direction.

Re: VA7410 device not ready
Shutdown and power off the array.
Take out the controllers, remove the battery for a while (I think they are empty anyway).
After some minutes put everythink back and start the array.
Connect a terminal to the serial ports, watch the status.
The controllers should get the config from the map-disks.
Do you have the commandview user guide?
It says about recovery:
"The armrecover reconstructs data mapping and array configuration in the
event of the loss of NVRAM contents. The data maps are reconstructed using
the latest copy of mapping information stored on the disk drives. Part of the
recovery operation includes performing a parity scan on the contents of the
entire array to validate the accuracy of the maps and to correct any drive
parity inconsistencies...."
Maybe this action is not needed at the moment.
Try to get some status information and post, I have no idea how the status looks like at the moment.
Hope this helps!
Regards
Torsten.
