I was wondering if somebody could point me in the right direction here.
The company I am working for needs to test I/O's to some SAN FC disk storage virtualization products. Does anybody know a program that does this function on OpenVMS 7.3-2 Perhaps there is a Decus program or a utility from lets say Diskeeper or I/O express etc... I have been away from OpenVMS for a while and do not know what HP or others could offer.
Thank you
Robert J.

- use volume shadowing to mirror two disks
- $ initialize /erase SAN_DISK: label
- use BACKUP /IMAGE or /PHYSICAL to read/write
- use "SYSGEN CREATE filespec"

Re: DISK STORAGE I/O TESTER DECUS or other Utility / Programs ?
The tests that I fell would be the best, are those that would be some sort of pattern test if possible i.e. write / read or compare type of program.
Does anybody know of such executeable programs out there? It could be a a DCL scripts as well.
Thank you again.

Re: DISK STORAGE I/O TESTER DECUS or other Utility / Programs ?
it all depends on 'what' you want to test. If you want to verify correct operation of read/write IO, a BACKUP/PHYSICAL/VERIFY or /COMPARE could be the right tool.
If you want to test performance, there is a TEST command in the DISKBLOCK utility (from OpenVMS Freeware CD).
I've also used DISKPERF for performance testing:

Google is your friend. TESTDEV should
work for you. I forget which freeware CD
it is on but you can google it.

Our good friend Hein, Vandenheuvel, who haunts this forum from time to time, has also been known to make the odd spindle groan under the load...
