Create a RAID 5 using Veritas

mynor aguilar_1 — Sat, 24 Feb 2007 10:50:44 GMT

Hello,
I'm trying to create a raid 5 on hp-ux 11.11 (3 disks) and veritas VxVM VxFS, I have a licenced product and i need to create the raid 5 (at disk level). So far, I just have seen how to create volumes on raid 5, but i want to put 3 disks on raid and not just a single volume.
regards,

Shalom,

Trying to do this will provide you no data protection. If you lose a disk it is likely you will lose data.

Without Veritas, I had to use a script to distribute the logical volume sections, rotating lvextend commands across 10 disks.

Veritas might have some internal rules about doing raid 5 on less than five devices.

Thanks steven,
So, what is the correct procedure to create a RAID5 on veritas, I thought that since i had 3 disk one of them would always have the parity needed to reconstruct the missing data. Anyway, is it correct to do it on a volume basis? how can i expand to my other disk (on raid 5) my rootDG?
right now veritas and HP-UX is installed on a single disk and needed to provide protection to my whole rootDG and the volumes on it.
