Resolving LVM errors from ipl_varyon -i

AIX – loopmount

Finally on aix 6.1 ibm have introduced mounting of iso directly without raw copy on lv:

Check if necessary loopback device is available

# lsdev -C | grep loop

if nothing returned, run:

# mkdev -c loopback -s node -t loopback
loop0 Available

If the device is not present on system you get this error:

1320-003 loopmount: Specified loopback device is not found in ODM

Now for mount:

# loopmount -i /iso/dvd.iso -l loop0 -o "-V cdrfs -o ro" -m /mnt/dvd

And umount:

# loopumount -l loop0 -m /mnt/dvd

Attention: an image file can be associated with only one loopback device.

AIX – lpp incosistent

# lppchk –v

lppchk: The following filesets need to be installed or corrected to bring the system to a consistent state:
9a33182fe26f1beae04e59e5cb6d3cdb 0.0.0.0 (COMMITTED)

# lslpp -L

Backup the ODM using the following command:

# tar -cvf /tmp/odm.tar ./etc/objrepos ./usr/lib/objrepos
# export ODMDIR=/usr/lib/objrepos
# odmget -q name= lpp
# odmdelete -q name= -o lpp
# odmdelete -q lpp_name= -o product
# odmdelete -q lpp_id= -o history
# odmdelete -q lpp_id= -o inventory
# export ODMDIR=/etc/objrepos
# odmdelete -q name= -o lpp
# odmdelete -q lpp_name= -o product
# odmdelete -q lpp_id= -o history
# odmdelete -q lpp_id= -o inventory
# export ODMDIR=/etc/objrepos

Check lppchk -v again to see if those entries are gone from ODM

AIX – Warning, savebase failed

0516-1734 extendlv: Warning, savebase failed. Please manually run ‘savebase’ before rebooting.

If you run savebase -v and you get “non-bootable LV name given” try reconstucting your /dev/ipldevice file.

Run savebase -v again and if you get the same error, try follow procedure:

# bosboot -ad /dev/hdiskX (a disk that has hd5 on it)
# bosboot -ad /dev/hdiskY (a disk that has hd5 on it)
# ipl_varyon -i

[You’ll get a return on every physical disk on the system]

You will then get a return similar to this:

# savebase -v

AIX – DLPAR connection lost to HMC

Sometime during AIX migration/alt_clone or HMC upgrade, it can happen that RMC ID get lost or duplicated, the the rsct process is unable to re stabilize the connection.

You can reset the key and restart that service as follows:

Reset RMC unique ID:

# /usr/sbin/rsct/install/bin/recfgct
# /usr/sbin/rsct/bin/rmcctrl -z
# /usr/sbin/rsct/bin/rmcctrl -A


Then you can check the rmc status:

# /usr/sbin/rsct/bin/rmcdomainstatus -s ctrmc

AIX – Mounting ISO images

There is a known problem with mounting ISO images on the AIX platform. To workaround the problem, complete the following instructions:

Obtain the size of the image, then identify the nearest multiple of 128 MB that will provide enough space for the image. For example, the image of CD-ROM is approximately 650/700 MB, so use 768 MB as an image size.

Make a logical volume of this size. Ensure that there is enough space on the physical volume. For example, hdisk0.

# mklv -y cdlv -s n -L /dev/cdlv rootvg 768M hdisk0

If the command fails, increase the volume size by a multiple of 128.

Use the dd command to create a pseudo-device. Ensure that the partition has enough space for the pseudo-device. In the following example command, the pseudo-device is /dev/cdlv.

# dd if=/opt/iso/cd.iso of=/dev/cdlv

Note that this command may take a long time and will create two dd processes.

Mount the device like a CD-ROM in AIX. Ensure that the mount point exists.

# mount -v cdrfs -o ro /dev/cdlv /mnt/iso

AIX LPAR – CDROM device relase

When AIX will not release /dev/cd0 device (after umount any associted filesystems), and you get busy device error on dlpar operations, use this command to kill all processes that take busy resource:

# fuser -k -x -u -c /dev/cd0

Usually in pSeries hardware configuration is connected to a scsi controller by scsi-to-ide/sas/sata or other terrible solution bridge.

To made all this operation faster you can identify pci parent adapter and remove recursively all device.

Identify:

# lsdev -l cd0 -F parent
scsi0
# lsdev -l scsi0 -F parent
sisscsia0
# lsdev -l sisscsia0 -F parent
pci10

Remove:


# rmdev -Rdl pci10
cd0 deleted
ses0 deleted
scsi0 deleted
sisscsia0 deleted
pci10 deleted

Then you can move the controller from HMC to another LPAR
