I would like to check how many SAS disks and its size per disk for the whole power system. As per my understanding, if we assign the SAS controller to LPAR, then we can see the disk in lpar smitty command.
How can we check from the Power machine(physical ones) as well? I think the power system should know how many disks it has and its size.
I have check in ASMI page, and in the console SMS, I can see some disks, but not see the size (screenshot attached).
I have two Unix machines on the network and now one of them are running out of disk but i have alot on the other so i like to mount the disk (or a folder) from the one that has disk and mount it on the other that does not.
How do i do that? Is it possible i read the "man mount" but didn't really... (5 Replies)
Hi!!
I am these days working on a project, where I need to know about the disk controllers available in a machine (e.g., 3ware,IBM,etc).
Please, let me know the command by which I can get the information.
thnx,

Hi,
Is there an easy way to find the disk-type from the command line or with another api ? sdparm works for SAS but not for SATA, hdparm works for SATA but not SAS.

hi guys,
I don't like the new concept of the power ha 7 cluster with the repository disk and the internal solidb, I really would like to mirror this disk, but the "IBM PowerHA SystemMirror 7.1 for AIX" redbook says, normal lvm operations should not be performed on this disk.

Hi,
I have installed the HMC on the VMWare VM. I try to add the power machine (managed system) and asking for a password? So this is the IBM predefined password of Power Machine?

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.
