Backing up an unmounted logical volume

[Timothy P. Jackson]

Hello everyone,

I am working on an Archive system that has Pick D3 on it. It is using lvol9 and lvol10 as its vertual hard drives. I need to get all the data off of these logical volumes and put them on another machine. Is there any way to do this other than the D3 applications backup? Because these logical volumes are not mounted, fbackup does not pick them up. Or, maybe I am doing some thing wrong.

Current OS - HP-UX 11.11 Version 1


Any help would be greatly appreciated!

If the volumes are not mounted, then there is no way to see them with your typical backup applications (fbackup, tar, cpio, pax). Your only option would be dd, but you would have to backup and restore the entire LV and you would not be able to see individual files in the backup.

I am assuming D3 manages the raw space and there is no mountable filesystems on these lvols. In that case, the (zero cost) choice is to use dd. The destination must be exactly the same size. Since the data must be transferred, you could create a network pipe, but if this is important data, use Data Protector.
