---------------------------------
This patch brings the
VRTSllt.rte fileset to 5.0.3.201 level
INSTALLING THE PATCHES IN VCS ENVIRONMENT
-----------------------------------------
The following steps should be run on all nodes in the VCS cluster:
Stopping the cluster:
-------------------
1. Offline all applications, which are configured on CVM/CFS
and are outside VCS control.
After all applications using CFS and CVM have been taken down,
run 'slibclean' to unload the libraries from memory.
2. Stop VCS on the current node.
# /opt/VRTSvcs/bin/hastop -local
Verify that ports 'f' (CFS), 'v' and 'w' (CVM), 'h' (VCS) have been closed,
# /sbin/gabconfig -a
The display should not have port 'f', 'v', 'w' and 'h' listed
3. If VXFEN is not configured, please go to step 5
4. Unconfigure VxFen:
# /sbin/vxfenconfig -U
Verify that port 'b' has been closed
# /sbin/gabconfig -a
The display should not have port 'b' listed
5. Unconfigure GAB:
# /sbin/gabconfig -U
6. Unconfigure LLT:
# /sbin/lltconfig -Uo
7. Unload the GAB driver:
# /etc/methods/gabkext -stop
Unload the LLT driver:
# /usr/sbin/strload -ud /usr/lib/drivers/pse/llt
8. Verify that the LLT driver has been unloaded
# /usr/sbin/strload -qd /usr/lib/drivers/pse/llt
/usr/lib/drivers/pse/llt: no
If llt is still loaded "yes" will show up in the output above.
Verify that the GAB driver has been unloaded:
# /etc/methods/gabkext -status
gab: unloaded
NOTE: If you are unable to successfully unload the LLT driver,
the server must be rebooted AFTER the installation of the patch.
This is so that the new LLT driver gets loaded in the AIX kernel.
Installing Patch on all nodes:
-----------------------------
1. Change directory to the patch location and install the LLT
patch from the bff files from the same location:
# installp -a -d ./VRTSllt.rte.bff VRTSllt.rte
2. Verify that the new fileset(s) has been installed:
# lslpp -l VRTSllt.rte

IBM, 9115-505
Re-starting the cluster:
-----------------------
1. Verify that the new LLT driver has been loaded:
# strload -qd /usr/lib/drivers/pse/llt
/usr/lib/drivers/pse/llt: yes
2. If not already loaded, load the newly installed LLT driver:
# strload -d /usr/lib/drivers/pse/llt
3. Configure LLT:
# /sbin/lltconfig -c
4. Verify that LLT has been configured properly
# /sbin/lltconfig
LLT is running
5. Configure GAB:
# sh /etc/gabtab
6. Verify that the GAB membership shows up correctly:
# /sbin/gabconfig -a
The display should have Port 'a' listed
7. Configure VxFen (if VxFEN was configured previously)
# /sbin/vxfenconfig -c
Verify that vxfen has been configured
# /sbin/gabconfig -a
The output should list port 'b'
8. Start VCS:
# /opt/VRTSvcs/bin/hastart
Verify that VCS is up and running:
# /sbin/gabconfig -a
The display should show port 'f', 'v', 'w' and 'h' listed.
The 'f', 'v' and 'w' port will be listed if CVM and CFS are configured.
9. Start applications (stopped earlier), which are outside VCS control.
Committing the Patch:
---------------------
1. To commit the patch:
(Note: The patch cannot be backed out once it is committed.)
# installp -c VRTSllt.rte
2. Verify that the fileset is committed:

UNINSTALLING THE PATCHES IN VCS ENVIRONMENT
-------------------------------------------
The VRTSllt.rte.bff patch can ONLY be backed out if it has not been committed.
NOTE: Before uninstalling patch, make sure that the APAR changing
DLPI behaviour is not installed on the system by running
following commands:
# instfix -iv | grep "BRING DLPI DRIVER "TO SPEC""
If above mentioned command returns an APAR then backing out
this point patch will move llt to older version, which will
cause panic or hang.
Steps to Backout the Patch:
--------------------------
1. Follow the steps provided under "Stopping the cluster" section above,
to stop the cluster & unload the drivers.
2. Backout the patches by the following command:
# installp -r VRTSllt.rte 5.0.3.201
3. Verify that the patch has been backed out:
(Note: The previously installed fileset(s) will be in committed state again.
It may differ from the mentioned, if a Hotfix was installed on top
of VCS 5.0MP3RP2)
# lslpp -l VRTSllt.rte

4. Restart the cluster following the steps under
"Re-Start the cluster" section above.
Note: The llt driver will now refer to the old one.
INSTALLING THE PATCHES IN SFRAC ENVIRONMENT
-------------------------------------------
The following steps should be run on all nodes in the cluster,
with SFRAC stack installed:
1. Offline all applications, which are configured on CVM/CFS
and are outside VCS control.
2. If Oracle database is not configured in VCS, stop it using following command:
$ srvctl stop instance -d <database name> -i <instance name>
3(a). For Oracle 9iR2, stop 'gsd' using the follwing command as Oracle user
$ gsdctl stop
To check the status of gsdctl, run the following command:
$ gsdctl stat
The gsdctl command is typically found in $ORACLE_HOME/bin.
3(b). For Oracle 10gR1 and 10gR2, Stop CRS manually,
if CRS is not under VCS control.
# /etc/init.crs stop
4. After all the oracle instances and other applications using
CFS and CVM have been stopped, run 'slibclean' to unload
the libraries from memory.
5. Stop VCS on the current node.
# /opt/VRTSvcs/bin/hastop -local
6. Verify that ports 'h', 'f', 'v' and 'w' have been closed
# /sbin/gabconfig -a
The display should not have ports 'h', 'f', 'v' and 'w' listed
7. Unconfigure VCSMM:
# /sbin/vcsmmconfig -U
Verify that port 'o' has been closed
# /sbin/gabconfig -a
The display should not have port 'o' listed.
If it does ensure that Oracle instances are offline.
8. Unconfigure LMX:
# /sbin/lmxconfig -U
9. Unconfigure VxFen:
# /sbin/vxfenconfig -U
Verify that port 'b' has been closed
# /sbin/gabconfig -a
The display should not have port 'b' listed
10. Unmount ODM:
# umount /dev/odm
Verify that port 'd' has been closed
# /sbin/gabconfig -a
The display should not have port 'd' listed
11. At this point all gab ports except port 'a' should have been closed
Verify this as follows:
# /sbin/gabconfig -a
12. Follow steps 5 to 8 of "Stopping the cluster" section from
"INSTALLING THE PATCHES IN VCS ENVIRONMENT" chapter above.
13. Follow all the instruction in "Installing the patch" section
from "INSTALLING THE PATCHES IN VCS ENVIRONMENT" chapter above.
14. Follow steps 1 to 7 of "Re-starting the cluster" section from
"INSTALLING THE PATCHES IN VCS ENVIRONMENT" chapter above.
15. Configure LMX:
# /sbin/lmxconfig -c
16. Configure VCSMM:
# /sbin/vcsmmconfig -c
Verify that vxfen has been configured
# /sbin/gabconfig -a
The output should list port 'o'
17. Mount ODM:
# mount /dev/odm
18. Start VCS:
# /opt/VRTSvcs/bin/hastart
19. Check if all ports are now open
# /sbin/gabconfig -a
The output should list ports
'a', 'b', 'd', 'f', 'h', 'o', 'v', and 'w'.
20(a). For Oracle 10gR1 and 10gR2, start CRS manually,
if CRS is not under VCS control.
# /etc/init.crs start
20(b). For Oracle 9iR2, start 'gsd' using the follwing command as Oracle user
$ gsdctl start
To check the status of gsdctl, run the following command:
$ gsdctl stat
The gsdctl command is typically found in $ORACLE_HOME/bin.
21. If Oracle database is not configured in VCS,
start it using following procedure.
$ srvctl start instance -d <database name> -i <instance name>
22. Online all applications, which are configured on CVM/CFS
and are outside VCS control (stopped earlier).
23. To commit the patches follow "Committing the Patch" section from
"INSTALLING THE PATCHES IN VCS ENVIRONMENT" chapter above.
UNINSTALLING THE PATCHES IN SFRAC ENVIRONMENT
---------------------------------------------
The VRTSllt.rte.bff patch can ONLY be backed out if it has not been committed.
NOTE: Before uninstalling patch, make sure that the APAR
changing DLPI behaviour is not installed on the system by
running following commands:
# instfix -iv | grep "BRING DLPI DRIVER "TO SPEC""
If above mentioned command returns an APAR then backing out
this point patch will move llt to older version, which will
cause panic or hang.
Steps to Backout the Patch:
---------------------------
1. Follow the steps outlined 1 through 12 of chapter
"INSTALLING THE PATCHES IN SFRAC ENVIRONMENT"
to stop and unload the drivers.
2. Backout the patches:
# installp -r VRTSllt.rte 5.0.3.201
3. Verify that the patch has been backed out:
(Note: The previously installed fileset(s) will be in committed state again.
It may differ from the mentioned, if a Hotfix was installed on top
of VCS 5.0MP3RP2)
# lslpp -l VRTSllt.rte

4. Next as before go through the process of loading and configuring
LLT, GAB and bringing up SFRAC (steps 14 through 23 above of
chapter "INSTALLING THE PATCHES IN SFRAC ENVIRONMENT").
Note: The llt driver will now refer to the old one.
