[Deepanpriyen]

Hi

I am doing vgexport

vgexport -v /dev/vgs01

Beginning the export process on Volume Group "/dev/vgs01".
/dev/dsk/c5t0d1
/dev/dsk/c7t0d1
vgexport: Volume group "/dev/vgs01" has been successfully removed.

after that ,

option 1:

I am importing with -s option and there is no error.

vgimport -v -s -m /tmp/mapfile2/vgs01.map /dev/vgs01
Beginning the import process on Volume Group "/dev/vgs01".

And the question is ...?



By the way, if you want to use the map file, you should create it during vgexport.

Hi

when i am using -s option, There is no issue.

and when i am importing with disk path, i am getting error.

what is the  reason.?

do my command in option 2 or 3 are wrong ?

[Torsten.]

As far as I can see you get a warning, not an error:

Volume Group belongs to different CPU ID.


The system knows the VG was created on another system. It cannot say if this other system has still access, so this check is up to you.

In option 1 when using -s you already specify the VGID you want to import, hence no warning.

[Patrick Wallek]

Did you actually run your 'vgexport' with the '-s' option?  I didn't see that from your output.

My preferred 'vgexport' command line:

# vgexport -v -s -m /tmp/file.map /dev/vgwhatever

The importing you can just do:

# vgimport -v -s -m /tmp/file.map /dev/vgwhatever

hi

i have done the exported the vg with -s option

vgexport -p -s -v -m /tmp/vgxx.map /dev/vgxx

and then imported in secondary node with

vgimport -s -v -m /tmp/vgxx.map /dev/vgxx

and with other option 2 and 3

i have done the vgexport without -s option

vgexport -p -v -m /tmp/vgxx.map /dev/vgxx

and then imported in secondary node with disk path

vgimport -v -m /tmp/vgxx.map /dev/vgxx

but without using -s option ,, i am getting warning message.

disk is shared between two nodes that i am cureently doing vgexport and vgimport.

same disk is presented to two nodes.

[Torsten.]

As said, the VGID is the key.

So your question is answered now?

[Deepanpriyen]

As said, the VGID is the key.

but still when i am able to do with -s option without  any warning in v2.

why can't i import with disk path without any warning in v3.

Hi all,

In option 3 the warning is that to take vgcfgbackup, this is general warning message. This can be neglected, but vgcfgbackup need to be performed.

In option 2 the error is ddue to one of the device file is not presented in that node, that's why on exclude the unwanted device vgimport has happened successfully in the option 3.

[taylor06]

the error in option 2 "vgimport: Warning: Volume Group contains "1" PVs, "2" specified. Continuing." clearly specifies .
