rx4640 EFI "Could not boot maintenace mode"

Hi, and welcome to the new forum.  I believe this was answered in the old IYRC forum, but, SURPRISE!  Can't find it.  So, I'll ask for the redundant solution.

 

I have an rx4640 that runs HP-UP 11iv2.  I'm trying to boot via the primary disk and am unable to.  I get the following message:

 

AUTO BOOT> boot vmunix -lq

Could not boot maintenance mode

 

If I issue the following command after that:

 

AUTO BOOT> boot

 

it just sits there and (if I remember correctly) dumps.

 

How can I get out of maintenance mode?  Is there a flag set somewhere that I am overlooking?

 

Thanks very much in advance for the help!

 

Dave

>> How can I get out of maintenance mode?

You are not in that mode.
The boot area is probably damaged and need to be repaired (use recovery shell from install DVD).

Hope this helps!

Re: rx4640 EFI "Could not boot maintenace mode"

LVM Maintenance Mode is accessed by running boot -lm  (not -lq), so the error is strange.

 

If you allow the autoboot to continue do you receive the same error message? 

 

Since you can access the HPUX> menu you have some means of of a boot loader installed on that disk.  Run the following to see what you see:

 

 HPUX> ll  (ell, ell)

You should a listing of your /stand filesystem with attributes.  Something like this:

 

dr-xr-xr-x   9 bin         bin            8192 May 24 15:34 ./
dr-xr-xr-x   9 bin         bin            8192 May 24 15:34 ../
drwxr-xr-x   5 root        sys            8192 May 18  2010 backup/
dr-xr-xr-x   3 bin         bin              96 May 18  2010 boot.sys/
-rw-r--r--   1 root        sys              21 May 18  2010 bootconf
lrwxr-xr-x   1 root        root             14 May 24 15:34 bootfs@ -> current/bootfs

drwxr-xr-x   2 root        root             96 May 18  2010 lost+found/
lrwxr-xr-x   1 root        root              7 May 24 15:34 nextboot@ -> current
-rw-------   1 root        root             12 May 24 15:33 rootconf
lrwxr-xr-x   1 root        root             15 May 24 15:34 system@ -> nextboot/system
-r--r--r--   1 root        sys            2611 May 18  2010 system.import
-rw-r--r--   1 root        sys            3553 May 18  2010 system.prev
-rwxr-xr-x   3 root        sys        65017104 May 18  2010 vmunix*

 

Also try:

 

HPUX> showauto

 

This tells you what the default boot 'string' is.  For example:

 

\EFI\HPUX\AUTO => boot vmunix

 

I might also confirm that you are booting to the correct disk.

Re: rx4640 EFI "Could not boot maintenace mode"

Thanks, Robert and Torsten.

 

 I tried to do the ll and it just hangs, so I think Torsten is correct in the assumption that the boot area is damaged.  I will use the Recovery Shell from the DVD to rebuild it.

 

I was thinking that it was a setting in the EFI where I was getting into maintenance mode, but it is actually with the LVM Manager, so I was actually outside the EFI.

 

Thanks for your help.  I should be able to muddle through the repair, otherwise you may hear from me again!

Re: rx4640 EFI "Could not boot maintenace mode"

The prompt you currently see

 

AUTO BOOT>

 

is the prompt of the boot loader hpux.efi.

 

From here the system will read the AUTO file and load the kernel.

 

If you have a problem with either the AUTO(start) file or the kernel (vmunix inside /stand), the system will stay at this prompt (with an error message).


Hope this helps!

Torsten.

Re: rx4640 EFI "Could not boot maintenance mode"

Yeah, you are right.  The prompt just hangs, so I do believe there is a disk problem.  I'm running the Recovery shell now.  I think I may just un-mirror a disk from a partner server, put it in this machine and re-configure it to be the new machine.

 

I'm going to play around with the recovery shell for a little bit, as it's all good practice for when a real event happens.

 

Thanks for your help Torsten.

Re: rx4640 EFI "Could not boot maintenance mode"

Take care, if you "unmirror" a set of disk, the "unmirrored" disk will not have any data anymore.

Hope this helps!
