migrating to new disk

Ed McKnight — Fri, 06 Jul 2001 18:36:27 GMT

I have a K260 with hp-ux 11. and 2 3312 jamaca's mirrored.
this started with 1 4gig disk each, the database got too big and the largest filesystem was moved to a new 4gig, again it grows and the largest filesystem is moved to a third 4gig, the first problem file grows and is extended to a 4th 4gig disk. now I arrive, I get 2 18gig disks I want to stripe these as one space and then allocate for the filesystems
first I want to move everything to the 36gig space and then stripe the 4 4gig's into 1 16gig then move some things back. PLEASE what is the most foolproof and least painfull way to do this! cpio, mirror, tape? all the mount points need to keep the orignal names i.e. /uvdata /uvdata2 /uvdata3....
this used to be the production system it is now the development/'failover' system but the production files are bigger than the filesystems. this is the reason to add lots of space. Thanks in advance. Ed

Hi there.
You should use the Logical Volume Manager
( LVM ).
This allows you to create logical volumes of the necessary size. You should spread the disks belonging to the lvols through different
scsi controlers and mirror the stuff if possible.
If oyu need more info, search the technicals documents for LVM.
