Best practices for additonal storage devices in a clustered container

Question

I am wondering what is considered as best practices related to adding more storage devices. I have a Solaris Cluster 3.2, a failover resource group with a SZBT resource and a HASP resource for the zone root path. Now i have to add more storage devices (for Oracle to the zone). The additional storage devices are in the same metaset as the zone root. I see the following options:
-> Add it to the zone (simple not managed by HASP)
-> Add it to the existing HASP for the RG and lofs mount it in the Zone (managed by HASP, but needs lofs mount)
Are there other options, and what is considered best practices?

Hi Fritz,
no matter which option you take it should resoult in lofs mounts.
I in person would not mix the concepts, you started with HASP, so I would continue with HASP.
To achieve this you have to take three steps:
1 add the file systems to the HASP resource,
2. create the mountpoints in the local zone
3 add the file system to the Mounts variable in the SCZBT's parameter file.
If you do not want to reboot the zones, you can mount the loopback files manually, but the safest option ( you will not mess up with typos in th mount pints and realize it later) would be to disable and reenable th sczbt resource.
