Maybe it's an extra I was not aware of. I only got to AIX 6.1 TL7 before the hosts were removed and it's not something I would have gone looking for, so thanks for teaching me something today.
What state are your disks in now? If the rootvg are real local disks, I presume you want them mirrored and both bootable. What do you have for the output of:-
Hi, I'm not good in scripting, maybe someone can help me.
I need to delete the lines that contains the last month date from a text file. Each line has the following date format:

Hi folks,
I known how to incrase and reduce File System size on AIX 5.3, but my issue is that I have a Logical Volume without any filesystem.
So, how to shrink just the logical volume ?
Thanks,

I have a script which includes an FTP. The filename is too long for my target area. The filename is HD012_ABCD_EFGH_061004_F_300_40. I need to the filename to be HD012_ABCD_EFGH_061004_F_. Any ideas. (5 Replies)
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)
Hi,
I've entered the HP-UX 11i server in single user mode, and increased the filesystem /usr by mistake using

I put small letter "l" instead of "L".

Hello
I have a question
I have a box with Aix 5.3 with rootvg on mirror.

My question is I can mirror this fs only ??? or I have to... (9 Replies)

Hi All,
We have a T5140 server which has 128 threads in total. Is it possible to reduce the number of threads per core through some configuration changes? I am sorry for being so naive but I am one on this.

vgchgid(1M)vgchgid(1M)NAME
vgchgid - modify the Volume Group ID (VGID) on a given set of physical devices
SYNOPSIS
PhysicalVolumePath [PhysicalVolumePath] ...
DESCRIPTION
The command is designed to change the LVM Volume Group ID (VGID) on a supplied set of disks. will work with any type of storage, but it is
primarily targeted at disk arrays that are able to create "snapshots" or "clones" of mirrored LUNs. accepts a set of raw physical devices
and ensures that they all belong to the same volume group, before altering the VGID (see section).
The same VGID is set on all the disks and it should be noted that in cases of multi-PV volume groups, all the physical volumes should be
supplied in a single invocation of the command.
Options
recognizes the following options and arguments:
PhysicalVolumePath The raw devices path name of a physical volume.
Background
Some storage subsystems have a feature which allows a user to split off a set of mirror copies of physical storage (termed or just as LVM
splits off logical volumes with the command. As the result of the "split," the split-off devices will have the same VGID as the original
disks. is needed to modify the VGID on the BCV devices. Once the VGID has been altered, the BCV disks can be imported into a new volume
group by using
WARNINGS
Once the VGID has been changed, the original VGID is lost until a disk device is re-mirrored with the original devices. If is used on a
subset of disk devices (for example, two out of four disk devices), the two groups of disk devices would not be able to be imported into
the same volume group since they have different VGIDs on them. The solution is to re-mirror all four of the disk devices and re-run on all
four BCV devices at the same time, and then use to import them into the same new volume group.
If a disk is newly added to an existing volume group and no subsequent LVM operations has been performed to alter the structures (in other
words, operations which perform an automated vgcfgbackup(1M)); then it is possible a subsequent will fail. It will report that the disk
does not belong to the volume group. This may be overcome by performing a structure changing operation on the volume group (for example,
using
It is the system administrator's responsibility to make sure that the devices provided in the command line are all Business Copy volumes of
the existing standard physical volumes and are in the ready state and writable. Mixing the standard and BC volumes in the same volume
group can cause data corruption.
RETURN VALUE
returns the following values:
0 VGID was modified with no error
1 VGID was not modified
EXAMPLES
An example showing how might be used:
1. The system administrator uses the following commands to create the Business Continuity (BCV or BC) copy:
1) For EMC Symmetrix disks, the commands are and
2) For XP disk array, the commands are and
Three BCV disks are created.
2. Change the VGID on the BCV disks.
3. Make a new volume group using the BCV disks.
This step can be skipped as the group file will be created automatically. If the file is manually created it will have different major
and minor numbers (see lvm(7)).
4. Import the BCV disks into the new volume group.
5. Activate the new volume group.
6. Backup the new volume group's LVM data structure.
7. Mount the associated logical volumes.
