If it refuses, try to remove the logical copy without specifying a disk. If it drops the copy on hdisk4 then use migratepv to move the LV from hdisk1 to hdisk4

I am hesitant to remove the jfs2log as i'm not sure what would be the outcome as I don't have a test server to try on.
New Question:
The purpose of an alternate disk install is in my opinion to have a ready-to-use-backup and i've read that it is possible to install filesets or software on the cloned disk for testing purposal while the normal system is still running.
The question is: how do you tell AIX (5.2... (5 Replies)
Hello
I have a question
I have a box with Aix 5.3 with rootvg on mirror.
I deleted a filesystem and I create a new one to install some software but when I type lsvg -l rootvg all my filesystems has mirror unless the new one.
My question is I can mirror this fs only ??? or I have to... (9 Replies)
I'm trying to troubleshoot an issue with an AIX system here. I have no experience with system administration of IBM stuff. Our local admin is ... um ... not available at this time.
I found something online that said enter service mode - How the heck do I do that??? Why is IBM stuff lack proper... (2 Replies)
When attempting to extend rootvg to a new physical disk I received the following message:

I would like to konw wheather below steps are sufficient for mirroring rootvg.
extendvg rootvg hdisk1
mirrorvg rootvg
bootlist -m normal hdisk0 hdisk1
bosboot -ad hdisk0
bosboot -ad hdisk1
or anything needs to be added. (7 Replies)
I want to increase the size of /tmp by 1GB
I know that the command is
chfs -a size=+1G /tmp
But the rootvg is mirrored and when I do a lsvg -p rootvg, I could see 2 disks.
Will there be any impact if I increase the size of /tmp when the rootvg is mirrored ?
Please advise. (1 Reply)
hello everyone, I have an AIX6.1 machine and i want to convert the rootvg to scalable format because i need to increase the size of specific file systems and i cannot do it with its current state. I know that in order to perform this operation the volume group must be varied off so is there a way... (5 Replies)
The root filesystem was mirrored, someone/something stopped mirroring, and increased / and /home to ridiculous values (/ got increased to 102gb and its only using 4.3gb, so 98gb is free). Can I reduce the / (/dev/hd4) filesytem down WITHOUT corrupting the the OS?
I would do a: chfs -a size=10g... (6 Replies)
Hi everybody,
I have a little problem with my AIX 6.1, PowerHA 6.1 LVM mirroring.
I accidentally created logical volume cpsabcd2lv with external jfs2log loglv00 in the same volume group cpsdata2vg. Then I mirrored LV cpsabcd2lv on the second LUN in VG cpsdata2vg. My journal is unmirrored and... (0 Replies)

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"
