make recovery failed

[Brent Hardesty]

I just ran make_recovery -v -A -d /dev/rmt/0m and received the following error:

make_recovery(390): Call to /opt/ignite/bin/save_config failed.

The makrec.log1 reads:
save_config: error - unknown disk type for /dev/vg00/lvol3, not SCSI or HPFL.

Can someone please help me resolved this issue? Currently, there is nothing mounted to this logical volume.

Thanks
Brent

/dev/vg00/lvol3 should be either / or /stand. Either way, it should be mounted. If you do a bdf does vg00/lvol3 show up? What does it show if you do an 'lvdisplay -v /dev/vg00/lvol3'? What type of disk(s) is your boot disk?

Hi Brent,

Just saw your question, I agree to what Patrick is saying and just want to add something to that. There is a document in the Knowledge tree here in the ITRC called 1100290244. This addresses this problem, it could depend on other things but might be worth a look. Another document is A5263022.

From document 1100290244:
*************
Perform the following steps to resolve the error:

1. Execute the save_config command:

/opt/ignite/bin/save_config
*****
see man page, you might need to use -f to specify filename if other than default is used.
*****
Note: This command gives more detailed error information:

save_config: error - unknown disk type for /dev/vg00/lvol3, not SCSI or HPFL

save_config: error - cannot determine primary swap size

You see the same error for lvol4.

2. Execute the bdf command to identify the lvol3 and lvol4 mount points.

Note: Root ( / ) is normally mounted at /dev/vg00/lvol3, and /opt is mounted at /dev/vg00/lvol4.

Perform the following steps if / and /opt are not properly mounted:

- mv /etc/mnttab /etc/mnttab.old
- mount -a

3. Execute the bdf command.

Note: bdf should now show the lvols mounted as /etc/fstab has them, and the make_recovery should work as expected.

Hope that this is of help to you.

One other thing to consider (not part of your original question) is your choice of using a no-rewind device.
Check the man page for make_recovery.
If you do not use a no-rewind device (dev/rmt/0mn), trying to recover from this tape WILL fail.

Good Luck!

Patrick:
bdf does not show vg00/lv0l3, I looked at my /etc/fstab and / should be mounted to vg00/lvol3. / is currently mounted to /dev/root/ (what does this mean exactly). Thanks for the help.

Johan:
Thanks for the note. You are correct, that is my problem / is not mounted correctly. I will do the mv and then the mount -a.

I have never found out what exactly causes / to be mounted as /dev/root. This URL gives as much information about this problem as I've seen anywhere, which is not much. http://us-support2.external.hp.com/cki/bin/doc.pl/sid=39d41da21c4b245465/screen=ckiDisplayDocument?docId=200000049506990

The basis fix is what is given in this document and in a previous response to your question.
