Guys can anyone tell how can we do faster disk cloning
Below i found in google
1. dd if=/dev/sda of=/dev/sdb bs=4096 conv=noerror,sync
So adding "conv=noerror,sync " makes it faster looks against not adding it
2. Enable write cache activated (hdparm -W1 /dev/sda) then run dd ..

hello folks,
I have a 300GB ROOTVG volume groups with one filesystem /backup having 200GB allocated space
Now, I cannot alt disk clone or mirrorvg this hdisk with another smaller disk. The disk size has to be 300GB; I tried alt disk clone and mirrorvg , it doesn't work. you cannot copy LVs as... (9 Replies)
I wasn't sure where to put this thread but since i use ubuntu for data recovery, I figured this is the best place.

Disk cloning
I had an external SCSI master disk that I used to clone to an identical external SCSI disk because the other SCSI disk would become corrupted. My original Master became corrupted so I used one of the other to good disk to copy back to the master. Unfortunately the new master needs... (1 Reply)

currently, this system only has one disk in it though. i do have the ability to hook up another disk via SCSI.
i have been told i need to boot to "miniroot" to run... (9 Replies)
metaimport(1M)metaimport(1M)NAME
metaimport - imports disk sets into existing Solaris Volume Manager configurations
SYNOPSIS
metaimport -s setname [-n] [-v] [-f] [disks...]
metaimport -r [disks...]
metaimport -V
metaimport -?
The metaimport command allows the importing of disk sets, including replicated disk sets, into an existing Solaris Volume Manager configu-
ration. Replicated disk sets are disk sets created using remote replication software.
The default Solaris Volume Manager configuration specifies a maximum number of disk sets that can be configured. The metaimport command
fails if importing the disk set would result in exceeding the number of disk sets configured on the system. To increase the number of disk
sets allowed on a system, see the .
Use metaset(1M) or metastat(1M) to view the configuration of the imported set.
You must run metaimport as root.
metaimport requires a functional Solaris Volume Manager configuration before it runs.
The following options are supported:
-f Force the import, even if a quorum of replicas from the imported disk set is not available. This option could
result in corrupt configurations and should only be used when metaimport fails with the "Insufficient quorum
detected; exiting" error. If only a partial disk set is available, this option might be necessary to successfully
import. Some or all data could be corrupted or unavailable when importing a partial set or a set lacking a replica
quorum.
-n Does not actually perform the operation, but shows the output or errors that would have resulted from the opera-
tion, had it been run.
-r Report on the non-configured disk sets found on the system. If no disk device or LUN is specified, metaimport
reports on all non-configured disk sets attached to the system. When the name of one disk is specified, metaimport
reports on the disk set (or virtual LUN) containing the specified disk. If two or more disks are specified, metaim-
port reports on the set (or sets, if they belong to different disk sets) containing the specified disks. If two or
more disks are specified, metaimport reports on the set (or sets, if they belong to different disk sets) containing
the specified disks.
-s setname Specify the disk set name to use when importing. The imported disk set will be called setname, without regard to
the name it may have had on a different system.
-v Verbose. Provides detailed information about the metadb replica location and status.
-V Version information.

Example 1: Importing a Disk Set
The following example creates a disk set called blue and identifies c1t5d0 as a disk containing a state database replica from the disk set
being imported.
# metaimport -s blue c1t5d0
Example 2: Reporting Disk Sets to Import
The following example scans all disks and LUNs attached to the system and configured as part of the system. It scans for disks that could
be part of a disk set to be imported. Components that are already part of the Solaris Volume Manager configuration are ignored.
This use of metaimport provides suggested forms of the metaimport command to use to actually import the disk sets that have been found. You
can specify a component on the command line to reduce the scope of the scan and generate results more quickly.
# metaimport -r
