Serviceguard fail over

[ckchai]

Hi,

My environment:-

3nodes cluster- HPUX 11.11

1st node - Oracle DB (instance name=CIM).
2nd node- Oracle DB (instance name=space).
3rd node - standby node.

I want to shutdown Oracle DB (space) at 2nd node to do maintenance. I also don't want the Oracle DB (space) at 2nd node to failover to the standby node. What is the correct steps that I should follow?

regards,
ck

CK,

If you halt the package manually, it should not fail over to the standby node.

Hi CK,

Just do the following

1. On node 2
cmhaltpkg -v

Once you complete the maintenance to start on node 2
cmrunpkg -v

Tip: IF you manually shutdown any package or a node, that will not failover.

Hope this helps

Sorry. I forgot to tell that, actually i did try to do the cmhaltpkg.
but once I cmhaltpkg, all the oracle DB files located at the quorum or shared disk is unmount.

Chan:- Are you saying that if i do a manual shutdown Oracle (shutdown immediate), the current cluster won't failover the application to the standby node?

Hi CK,

which version of the enterprise toolkit is using?

if you want to have the shared disk mounted, there is couple ways to do it.
1. shutdown the oracle package and then manually activate the VG and mount the FS.

2. there is a bypass flag in the new version of ETK. Touch the flag in the oracle package directory and it will bypass the monitoring of the oracle processes.... then shutdown the oracle to do the maintenance.
remove the flag after startup the oracle.

GOOD LUCK!!

It depends on the controls you implemented.

I suggest you (to have a cleaner Service Guard status) to halt the package (cmhaltpkg) and activate manually the volume group/s (vgchange -a e) and mount the filesystems, if you need them mounted.

Once done, unmount fs and deactivate vg.

Regards.

CK,

BTW, as I remember, there is infomation in the master toolkit readme file .

check the /opt/cmcluster/toolkit/oracle/readme...

GOOD LUCK!!

CK,

Check that your oracle DB or applications are not being monitored, you can work without shutting down the package.

Once that cluster package is running, do an oracle shutdown and do your maintenance.

Hi CK,

If the 2nd node will be halted you need to fail over the package which residing from it to another node so the production from the package will not be affected. Much better to fail over the package from 2nd node into primary node.

CK,

If you dont want the package (space) to failover to other node, do a cmmodpkg -d space. and then you can do cmhaltpkg. other wise if you do a cmhaltpkg without disabling the auto failover it will failover to the adoptive node if you just halt the pkg or node.
