Start up help neeed

Hello,

Total Unix dummy here. My company runs an older UNix networking server. It's done a great job for us until today, when on re-boot we recieved this message:

Notice: sysdump-init: Memory size is larger than the dump device panic dump will be selective.

vxvm:vxconfigd: warning: detaching rootvol-01 from volume rootvol
vxvm:vxconfigd: error: system boot disk does not have a valid rootvol plex
Please boot from one of the following disks:

Disk: rootmirror Device: c1b0t10d0s0


Can anyone shed any light on what happened and suggest a course of corrective action?

Thanks in advance.

Forgive me if this not correct as I am new to UNIX but long time user and admin using Linux.

What versino of UNIX are you running?

Approaching this problem by reading what you stated would suggest a few things.

1. Notice: sysdump-init: Memory size is larger than the dump device panic dump will be selective.

>> This looks like it is saying that your servers memory is greater than the hard disk storage that is available. So, if a panic occurs, only selected data will be able to be dumped since there is not enough storage to accept the full dump.

2. vxvm:vxconfigd: warning: detaching rootvol-01 from volume rootvol
vxvm:vxconfigd: error: system boot disk does not have a valid rootvol plex
Please boot from one of the following disks:

Disk: rootmirror Device: c1b0t10d0s0

>> This shows that the rootvol-01 has been removed from the system. You may want to check and see if you are having a hard drive failure, file system corruption, partition corruption. Your system will not boot because it does not see a valid boot disk to load the system. Since you said that the system was older, I would check to see if your hardware is still fully functional.

>> Has your system been moved, upgraded, and had work done on it recently? It is looking for a rootmirror device with a certain ID and once it does not find it, it fails. Are you using some type of RAID configuration?

Finally, Do you have backups in place so in the case of a hardware failure you can restore the data and move forward.

Hope this gets your thinking on the right track. As I am eager to advance my learning, if someone with more experience can comment.

Hi Patrick,

Hope you already solved the issue as it's never nice to have a system down and don't know how to get it back online.

The first error of "dump device too small for memory..." Is ok, you have solaris runing or an older version of Sun OS. You probably have upgaded memory, but never the swap-space and /var/adm/crash. Anyway it's not the most critical message.

The otherone is. Your system cannot determine what the boot-disk is and where it should boot of. This might be caused by a wrong setup in de boot-prompt or an error with the disk.

printenv boot-device
should show you the order of booting from the "ok"-prompt as it lists the devices by nick-name.
devaliases should show you the correct paths, these patchs should lead you to the root-disk.

By making it very easy you could just type in :

boot c10t10d0s0
or
boot mirror
or
boot <other names that come up from the printenv command>

Else you'll have to discover the hardware path of the boot-disk. You probably need help of an advanced person onsite to fix this. Booting from CD and fsck the FS each by each could be a solution as well.

Please let us know if you still have this problem. If so please add a printenv output, and we will be able to help you further.

Thank you all for your input, it has been most helpful.

The system isn't up yet, but I called in an army of techs and they are crawling over it this morning. As it happens, you analysis was dead on- I am waiting to see if it was a hardware failure or simply a matter of the boot drive maintenance being negleted for ohh....three years.....and the disk being so full as to prohibit proper start up.Smilie

Obviously I am not an IT person, we're just a little company (who was about to upgrade our entire network, as it happens---I think the computer gods took a hand).

I'll update you all when I get more inof.

Thanks so much!
