Solaris

Hello all,

I have a Solaris Disksuite question :-

I will be adding 4 new drives to an E250 server and need will be configuring 2 striped volumes each consisting 2 new disks with SVM. In the end i will have 2 volumes each of 72gb. So in effect i will have 1 volume called D7 and another volume called D8 consisting of 2 drives each.

Question is, can i mirror these volumes with each other ?

I have had a look around to find the answer and although i will be using SVM to create the 2 striped volumes, can i also use SVM to mirror these volumes with each other, or do i need to use RAID 5.



Many thanks for your response.

Yes you can. This is recommended way of building mirrored volumes (using concatenations/stripes instead of using physical disks directly).

So i can use the D7 and D8 already created volumes to mirror each other by means of :-

metainit d51 1 1 d7
metainit d52 1 1 d8
metainit d50 -m d51
metattach d50 d52

Well, I think d51 and d52 should be created on physical disks, like:

Code:

metainit d51 1 1 c0t0d0s0
metainit d52 1 1 c0t1d0s0

If you want to have 2 concats each consisting of 2 disks, then use:

Code:

metainit d51 2 1 c0t0d0s0 1 c0t1d0s0
metainit d52 2 1 c0t3d0s0 1 c0t4d0s0

Yes, but that does not mirror the volumes containing the 2 disks.

I can create the volumes using the 2 disks, no problem, concat or stripe.

My issue is that want to mirror the 2 volumes created.

Can this be done ?

Thanks

Code:

metainit d51 2 1 c0t0d0s0 1 c0t1d0s0
metainit d52 2 1 c0t3d0s0 1 c0t4d0s0
metainit d50 -m d51
metattach d50 d52

This will create 2 concat volumes AND mirror them.

Ok, i'll try that, many thanks.
