Smitty

This scenario applies only to the update or installation of optional software products. If you’re AIX 5L Version 5.3 BOS installation was unsuccessful, Note: It is recommended that you first perform a system backup before installing software updates to ensure safe system recovery.

The cleanup procedure attempts to revert the update to its previous state. For example, when cleaning up an update that was interrupted in the COMMITTING state, the cleanup procedure attempts to return the update to its APPLIED state.

If an update installation is interrupted, run the lslpp -l command to see the current state of the update. For example, if you run lslpp -l on an interrupted update installation, it might report the update status as APPLYING rather than APPLIED.

If the interruption occurs during the initial state of an installation, then the cleanup procedure attempts to delete the installation entirely and restore the previous version of the product (if there is one). When the previous version is restored, it becomes the active version. When the previous version cannot be restored, the software is listed by the lslpp -l command as BROKEN.

When the product is deleted or BROKEN, you can attempt to reinstall the software. Any product in the BROKEN state cannot be cleaned up; it can only be reinstalled or removed.

To initiate a cleanup procedure using SMIT:

1. Type smit maintain_software on the command line.
2. Select Clean Up After Failed or Interrupted Installation and press Enter.

To initiate a cleanup procedure from the command line, type installp -C on the command line and press Enter.

If prompted to reboot (restart) the system after running the cleanup procedure, then do so now.

If you get a message indicating that no products were found that could be cleaned up, you might have executed the cleanup procedure when it was not needed. Try your installation again.

• Mirror the logical volumes:

a. If you don’t care what disks the lvs get mirrored to, execute

mirrorvg rootvg

b. Otherwise:

for lv in $(lsvg -l rootvg | grep -i open/syncd | \
grep -v dumplv | awk ‘{print $1}’)
do
mklvcopy ${lv} 1 ${disk}
done

• Change the quorum checking if you did not use mirrorvg:

chvg -Q n rootvg

• Run bosboot on the new drive to copy boot files to it:

bosboot hdiskx

• Update the bootlist with the new drive:

bootlist -m normal hdisk0 hdisk1

• Reboot the system to enable the new quorum checking parameter

1. backup data you intend to migrate
2. unmount fs where lv resides
3. copy the source logical volume to the desired volume group with the cplv
command.
For example, where myvg is the NEW volume group and mylv is the name of
the user’s logical volume, enter:

cplv -v myvg mylv

4. All JFS require a log device. If JFS log does not already exists on the
new volume group,

mklv -t jfslog myvg 1

This will return a new jfslog such as loglv00. This will need to be
reformatted with the
logform command to function as a JFS log.

logform /dev/loglv00

5. Change the filesystem to reference a log device that exists in the new vg
and the new
logical volume with the chfs command.

For example where myfilesystem is the name of the user’s filesystem,
enter:

chfs -a dev=/dev/lv00 -a log=/dev/loglv00 /myfilesystem

6. RUn fsck to ensure filesystem integrity,

fsck -p /dev/lv00

7. Mount the file system. For example, where myfilesystem is the name of the
user’s
file system, enter:

mount /myfilesystem

At this point the migration is complete and any applications or users can
now access the
data in this filesystem. To change the logical volume name, proceed to
step 8. Note: If  you receive errors from the preceding step do not continue, contact AIX
support center.

8. Remove the source logical volume with the rmlv command:

rmlv mylv

9. Rename and reset any needed attributes on the new logical volume with the
chlv or chmod commands.

For example, where mylv is the name of the user’s logical volume, enter:

chlv -n mylv lv00
