You can create a mirrored zfs setup, however, there is something to note. It is disk for disk mirroring at the zpool level so you create mirrored storage, not mirrored filesystems, and it is not possible to detach one complete mirror as the zpool mirroring forces a RAID 0+1 configuration.
For example:
would create a zpool called mypool where c0t0d0 mirrors c0t1d0 and c1t0d0 mirrors c1t1d0
You would then use :
to create a zfs filesystem on the mirrored pool and
To set the mountpoint of the filesystem to /applications.
Being somewhat extremely new to Unix, I have just had a system crash
One of my Volume Groups has crashed
However, this Volume Group is actually mirrored
How do I switch to use the mirrored copy?
Any assistance greatly appreciated

Hi,
need some help.
I’m new to solaris and trying to find out how to mirror a data disk (not the root disk).
In AIX it is easy but with solaris 5.8 I don’t find my way even with the SUN docs (disk/suide is installed).
What is behind is I want to migrate a disk from 1 storage system to... (7 Replies)
Hello,
I've got 2 system disks (hdisk0 and hdisk1) in the mirror (RAID1) on AIX 5.3. Since the hdisk1 makes some troubles, we want to replace it with the new one. How can I disable this hdisk1 disk and prepare the mirror to use the new physical disk? As far as I know, I must remove disk from the... (3 Replies)
I've looked a little but haven't found a solid answer, assuming there is one.
What's better, hardware mirroring or ZFS mirroring? Common practice for us was to use the raid controllers on the Sun x86 servers. Now we've been using ZFS mirroring since U6. Any performance difference? Any other... (3 Replies)

hello folks,
I have a 300GB ROOTVG volume groups with one filesystem /backup having 200GB allocated space

I have Solaris-10 (release-7) box without any non global zone. I have a very critical change after couple of days from application side. For safer side, we want to keep few level of backups just in case of faliure. This server is having three pool

Hello,
I am upgrading Veritas from 5.1 to 6.0.1/6.0.5 in a Solaris 10 u8 server with OS mirrored (rpool) in zfs/zpool configuration.
I need to split it to have a quick way to backout in case of failure (make splitted mirror side bootable for a quick revert, like booting from it). I remember... (3 Replies)

raidctl
raidctl(1M) System Administration Commands raidctl(1M)NAME
raidctl - RAID hardware utility
SYNOPSIS
raidctl -c disk1 disk2
raidctl -d disk1
raidctl [-f] -F filename controller...
raidctl -l [controller...]
DESCRIPTION
The raidctl utility creates, deletes, or displays RAID volumes of the LSI1030 HW Raid controllers that include RAID support. The utility
also updates firmware/fcode/BIOS for both RAID and non-RAID controllers.
The raidctl utility requires privileges that are controlled by the underlying file-system permissions. Only privileged users can manipulate
the RAID system configuration. If a non-privileged user attempts to create or delete a RAID volume, the command fails with EPERM.
Without options, raidctl displays the current RAID configuration on all exisiting controllers.
OPTIONS
The following options are supported:
-c disk1 disk2 (for on board)
Create a mirror using disk1 and disk2. Replace the contents of disk2 with the contents of disk1. Specify disk1 and disk2 in canonical
form, for example, c0t0d0.
When you create a a RAID volume, the RAID volume assumes the identity of the first target in the disk pair (disk1). The second target
(disk2) disappears from the system. Therefore, the RAID volume appears as one disk.
To have a successful RAID creation, there must not already be a RAID configuration present on the specified controller. Additionally,
the secondary disk must not be mounted, as it has all its data erased and replaced with the primary disk's data.
-d disk1 (for on board)
Delete the RAID volume specified as disk1.
Specify disk1 in canonical form, for example, c0t0d0.
-f (for HBA)
Force an update. Do not prompt.
-F filename controller (for HBA)
Update the firmware running on the specified controller (controller).
-l [controller ...] (for on board)
List the system's RAID configuration. If controller is specified, list RAID configurations for controller.
Output from the -l lists the following information:
RAID Volume Displays logical RAID volume name.
RAID Status Displays RAID status as either RESYNCING (disks are syncing), DEGRADED RAID is operating with reduced functionality),
OK (operating optimally), or FAILED (non-functional).
RAID Disk Displays RAID disk name.
Disk Status Displays disk status as either OK or FAILED.
EXAMPLES
Example 1: Creating the RAID Configuration
The following command creates the RAID configuration:
# raidctl -c c0t0d0 c0t1d0
RAID Volume 'c0t0d0' created
Example 2: Displaying the RAID Configuration
The following command displays the RAID configuration:
# raidctl
RAID RAID RAID Disk
Volume Status Disk Status
----------------------------------------
c0t0d0 RESYNCING c0t0d0 OK
c0t1d0 OK
Example 3: Deleting the RAID Configuration
The following command deletes the RAID configuration:
# raidctl -d c0t0d0
RAID Volume 'c0t0d0' deleted
Example 4: Updating Flash Images on the Controller
The following command updates flash images on the controller:
# raidctl -F lsi1030.fw 0
Update flash image on controller 0? (y/N): y
Flash updated successfully
EXIT STATUS
The following exit values are returned:
0 Successful completion.
1 Invalid command line input.
2 Request operation failed.
