I could probably throw my two pennies in here as I recently mirrored my Solaris 10 system (Intel) via the command line. There are many problems with this, regarding uncontrollable kernel panicking if a disk fails due to the fact the thing is trying to write to the UFS log on the defective disk - but on Intel the workaround provided by Sun doesn't workaround the problem so there are more issues... Smilie

Anyway, I have written everything up in this article in the hope that it'll save others the hours of head scratching that I endured.

Ta,

MySQL sheesh

I am running two x4200's on sol 10 and this problem has been killing me. I hope what I find works...if so, I'll do a write up too.

Thanks all.

Solaris 10 internal disks can be mirrored using hardware raid no specific external software is required for that
For example my solaris 10 internal disks are harware mirrored like the following
$ raidctl
RAID Volume RAID RAID Disk
Volume Type Status Disk Status
------------------------------------------------------
c0t0d0 IM OK c0t0d0 OK
c0t1d0 OK

If you have any array then it is a different thing
you can either use Solaris Disk Suite or Veitas Volume Manager
If it is one of the newer arrays though you can use VxVm but sun recommends using the software provided witht the array

That depends entirely on the hardware being used. It is by no means true that Solaris 10 is the enabler for this, Solaris simply provides the tools with which to manipulate some hardware that is capable of RAID.

MySQL hmm

I have found that the key to setting up RAID 1 with svm (sds) is to CONTIGUOUSLY layout the file systems during "from dvd" install on these x4200's. This has been painful, but its interesting. I still cannot tell how many gigs/megs/k a cylider equals with 8,923 cylinders on a 70G SAS drive.

I did get it all up and running using svm (metadb, metainit, metaroot, etc)

Hi

Isn't supposed that ZFS can help with that task ? I'm trusting in ZFS mirror to configure some of my customer Solaris 10 systems, of course data pools. For OS i still trust in DiskSuite.

Hope this helps
