Environment HPUX 11:31 Oracle 11.1.0.6 ASM HP Superdome XP Array Storage Application - Data warehouse ~15TB
We are being advised by 3rd party consultants to install HP SLVM (shared volume manager) to present the disks to ASM and use ASM for disk management.
The advantages are supposed to be
- If we ever go to a clustered system/database then having SLVM will be an essential building block in building Service Guard
- It allows the Unix team to 'see' disk usage without using asmcmd
I see 1) as an irrelevancy as if we do go to SG (highly unlikely as there is no business requirement) then we would use RAC as well and therefore that would be time to re-design the application and disk layout anyway.
2) has some merit but I am worried about supportability from Oracle if we have any disk issues.
Does anybody know of a similar setup or have any thoughts on the matter
Thanks
John
