LUN issue.

[fizan]

issue is the ignite recovery we have done and the vg's also copied in the /dev but its not getting activated, due to the vg's are from the storage, so i will do

1.delete all the storage vg's inside /dev (files)
2. configure the lun and assign it to the server
3. ioscan the hdd and pvcreate that disk and add in the vg
4.now create the LV with the extended hdd
then newfs and mkdir /test and mount it right.

thanks

For #1 do not delete the /dev/vg files. Use vgexport to delete the volume groups.

Hi

You do not have data in that VG?
if you do not have then this is oK or of the data is not required.

alternatively you can try the following

vgexport /dev/
mkdir /dev/
mknod group c 64 0xYY0000
the major number should be unique
you can set this to a value not matching with
ll /dev/*/group

then vgimport using the map file you have

#vgimport -v -s -m /dev/
Or
#vgimport -v -f /dev/

see man 1m vgimport for more of the options

this only shows

What kind of "storage" are you looking for?



This is a USB connected CD-ROM in an older version of 11.31:
