SGeRAC 11.17 + Oracle ASM over SLVM + Oracle 10g RAC

[nm76]

Hi,
I was wondering whether anyone has been through the following type of configuration:
.
1. HP-UX 11.23 (PA-RISC 64 Bit)
2. Oracle 10gR2 (10.2.0.2)
3. Oracle ASM for database storage
4. Serviceguard Extension for RAC 11.17
.
It is my understanding that deploying 10g rac on hp-ux when serviceguard is in use, requires that asm be delployed over slvm. I was wondering whether anyone has done something like this? Or perhaps at least deployed Oracle ASM over SLVM. Juts wondering if any major issues where faced, or if you would be kind enough to share any tips?
Thanks

With slvm you do not necessarily need oracle ASM except for the oracle cluster read services.

thanks for the info. I've had a look at those docs and a few others too.
It is my understanding, that in order to implement ASM for 10gR2 rac, SGeRAC 11.17 is required, and that asm be implemented over SLVM.
Just wondering if anyone has implemented ASM over slvm?

Yes, I installed once.
How many servers do you have?
What model of HP9000 your servers are?
What kind of HP-UX do you have? (FOE, EOE, MCOE)
Do you have any special problem or you just asked about possibility of this scenario?

Hi,
Thanks for the update. I was wondering if anyone has done this and if they faced any problems? I should be starting this today or tomorrow and was just wondering about other peoples experience on this type of deployment.

Hi

To implement ASM you dont need service guard. To implement ASM over SLVM you need service guard. With out service guard you wouldn't be able to share the VG between cluster members. Since you use 10g R2 database, hopefully you will be using CRS & ASM also R2.
As the R1 version of CRS and ASM has lots of issues.
If you use ASM you should look of RMAN backup solutions only not the fbackup, vxdump for your cold backup but still you can use the dd for the cold backup.

thats nk for the update. Yes we will be using 10gR2.
I was wondering, for anyone who has done this, or even anyone who has deployed 10gR2 with serviceguard. Is there a need to disable the oracle clusterware for restarting after a reboot - through:
.
crsctl disable ?

Yes you do need to run that command - in the last few weeks HP have released a toolkit which completex this integration fairly painlessly.

Thanks for update. This is what I see the toolkit acheiving:
.
1. SGeRAC startsup checks storage availability
2. SGeRAC starts oracle clusterware
3. Oracle clusterware starts its node applications, which are:
gsd,ons,vip,network listeners and asm instances
4. SGeRAC will then start the rac database
.
My question, is this, to anyone who has implemented this. When certain components have their control put under SGeRAC like the database - or the rac instances. When one instance is manually shutdown lets say via 'srvctl' would SGeRAC try to restart this instance that is now being shutdown?
