lvcreate extent based striping on non-mirrored data disks

[Glenn Mitchell_2]

Can the lvcreate option -D work on a non-mirrored lvol?

I will be performing a disaster recovery test of my HPUX 11.11 N4000 system with mirrored extent based striped lvols to another HPUX 11.11 N4000 with non-mirrored data disks. After vg00 is recovered using my ignite tape I will have to create the LVM structure. The original database lvols were created using the command:

lvcreate -D y -s g -n db1 /dev/vg01

...and then lvextended to develop mirroring.
Question: Should I use the same command on the disaster recovery system, without the mirroring - or just use the -i and -I options?

You could do it either way. You would probably get better performance using -i and -I if you don't care about mirroring.

The command you give will work fine. You do not *have to* mirror extent-based stripes. They were developed to allow you to have mirrored striped of a sort.
