AIX Backup Logical volume
I'm running aix 5.3 ml 5
I have one uservg that has 2 hard disks ( hdisk1 and hdisk2) inside it.
hdisk1 has error reported and need to be replaced.
in hdisk1 has all logical volume not be mounted ( i dont know it is previously mounted or not coz this is old project system) and i dont know what the filesystem name is.
and hdisk2 has the paging space and 1 logical volume that been mounted to filesystem.
the problem is ... Is it POSSIBLE to back up LOGICAL VOLUME not filesystem in hdisk1 using savevg cmd or any other cmd that i do not know?
i want to back it up to a tape.
Thank you.

Please post results of "lsvg", "lsvg -o" and "lsvg -o | lsvg -i -l".
And "lsvg -p hdisk1" and "lsvg -p hdisk2" also.

Ok - the data on hdisk1 is not mirrored to hdisk2. If the disk fails then data will be lost.
You cannot backup the content of a raw LV with savevg. If you have enough disk space in sybasevg on hdisk2 I recommend adding a mirror copy of each LV on hdisk1 to hdisk2. If you do not have space you should bakup the data via the application which uses the data (Sybase?). As a last resort, you may copy a raw LV to tape with "dd" but this is not a very good solution as you will need to copy the whole of the LV to tape.

can you show me how to use the command dd to copy the whole LV to tape?
because i have no enough space in hdisk2.
