I have question and I want some one to answer it ..
in Solaris 10 I have two mirrors as below .. c3t0d0s0 & c3t1d0s0
I'm planning to keep the second mirror which is c3t1d0s0 to have a healthy copy of the OS and I'll detach it and I'll mirror it every week one time to be healthy OS copy for me and fast roster backup for me if any thing happen for the first mirror.
which is mean it'll be all the week detach and in the end of week I'll attache it to have full mirror then I'll detach it again
is there any problem to keep my system running with one mirror and another one will be mirrored every one time every week ?
Pls advice in this regard ..

Hi everyone.
I have a Sun Solaris box which is running on only one internal disk and obviously that is not a good thing, if the disk should fail. This is a pritty straight forward operation in AIX, where my experties are. I have never done this in solaris and would therefore appriciate any help... (3 Replies)

Hi All,
How do I break the solaris 8 mirror? And how do I make sure I will point the first hd mirror on reboot.
If the first break mirror won't boot. How do I make the copy mirror to boot?
Thanks in advance,

I’m setting up a boot disk mirror on Solaris 10 x86. I’m used to doing it on SPARC, where you can copy the partition table using fmthard. My x86 boot disk has 2 primary partitions, a Solaris one and a diagnostic one. Is there a way to copy those 2 primary partitions to the second disk without... (6 Replies)

lvconvert
LVCONVERT(8) System Manager's Manual LVCONVERT(8)NAME
lvconvert - convert a logical volume from linear to mirror or snapshot
SYNOPSIS
lvconvert -m|--mirrors Mirrors [--mirrorlog {disk|core}] [--corelog] [-R|--regionsize MirrorLogRegionSize] [-A|--alloc AllocationPolicy]
[-b|--background] [-i|--interval Seconds] [-h|-?|--help] [-v|--verbose] [--version]
LogicalVolume[Path] [PhysicalVolume[Path]...]
lvconvert -s|--snapshot [-c|--chunksize ChunkSize] [-h|-?|--help] [-v|--verbose] [-Z|--zero y|n] [--version]
OriginalLogicalVolume[Path] SnapshotLogicalVolume[Path]
DESCRIPTION
lvconvert will change a linear logical volume to a mirror logical volume or to a snapshot of linear volume and vice versa. It is also used
to add and remove disk logs from mirror devices.
OPTIONS
See lvm for common options.
Exactly one of --mirrors or --snapshot arguments required.
-m, --mirrors Mirrors
Specifies the degree of the mirror you wish to create. For example, "-m 1" would convert the original logical volume to a mirror
volume with 2-sides; that is, a linear volume plus one copy.
--mirrorlog {disk|core}
Specifies the type of log to use. The default is disk, which is persistent and requires a small amount of storage space, usually on
a separate device from the data being mirrored. Core may be useful for short-lived mirrors: It means the mirror is regenerated by
copying the data from the first device again every time the device is activated - perhaps, for example, after every reboot.
--corelog
The optional argument "--corelog" is the same as specifying "--mirrorlog core".
-R, --regionsize MirrorLogRegionSize
A mirror is divided into regions of this size (in MB), and the mirror log uses this granularity to track which regions are in sync.
-b, --background
Run the daemon in the background.
-i, --interval Seconds
Report progress as a percentage at regular intervals.
-s, --snapshot
Create a snapshot from existing logical volume using another existing logical volume as its origin.
-c, --chunksize ChunkSize
Power of 2 chunk size for the snapshot logical volume between 4k and 512k.
-Z, --zero y|n
Controls zeroing of the first KB of data in the snapshot. If the volume is read-only the snapshot will not be zeroed.
Examples
"lvconvert -m1 vg00/lvol1"
converts the linear logical volume "vg00/lvol1" to a two-way mirror logical volume.
"lvconvert --mirrorlog core vg00/lvol1"
converts a mirror with a disk log to a mirror with an in-memory log.
"lvconvert --mirrorlog disk vg00/lvol1"
converts a mirror with an in-memory log to a mirror with a disk log.
"lvconvert -m0 vg00/lvol1"
converts a mirror logical volume to a linear logical volume.
"lvconvert -s vg00/lvol1 vg00/lvol2"
converts logical volume "vg00/lvol2" to snapshot of original volume "vg00/lvol1"
