lvm/vxvm

[Shiva123_shan]

Hi,

We have an itanium servers rx4640 running HP-UX 11.23 and rx6600 running 11.31. These servers have veritas to manage data disks(vxvm with vxfs). Now we have to rebuild 2 more servers that will replace these 2 servers.

The new servers are not going to use veritas. We are going to restore the data file systems to lvm/vxfs on the new servers. Will it be a problem..? will the restore work fine in the new servers? Please advice.

Appreciate your help. Thanks

Without more details it is difficult to answer.

- What backup software are you going to use to restore the data filesystems? A regular file-based backup should not care about the difference of LVM vs. VxVM when restoring the filesystem contents. For more specialized backup solutions it might be different.

- Before the introduction of LVM 2.x in HP-UX 11.31, VxVM was needed for huge volume groups (larger than 16 TB). Even though the maximum size of a LVM 2.x LV is at 256 TB or more, VxVM might still be preferred as a well-known and proven way to manage huge  amounts of data. How much data are you going to restore?

Hi mk,

Thanks for the reply, much appreciated, going to restore 50g to 2 tb file systems. The data file systems are backed up and the restoration will be performed by netbackup server. Normal file backup. No special backups/ restore needed.

Thanks Again
