Testing HBAs

B Wade Moll — Thu, 17 Jul 2008 17:27:09 GMT

Am experiencing performance issues with new 11.23 database server. Have checked LAN speeds, kernel settings and verified that Oracle settings are correct.

I would like to verify that my dual HBA's to the array are running at proper speeds, and to turn each one on and off to see if this makes a differnce in performance.

Is there a procedure to use to verify HBA speed and to toggle them on and off to force traffic to use specific channels to the array?

Thank you !!

Try this:

# fcmsutil /dev/fcd0

Vendor ID is = 0x001077
Device ID is = 0x002422
PCI Sub-system Vendor ID is = 0x00103c
PCI Sub-system ID is = 0x0012d6
PCI Mode = PCI-X 266 MHz
ISP Code version = 4.0.91
ISP Chip version = 3
Topology = PTTOPT_FABRIC
Link Speed = 4Gb
...

Is there a way to down an HBA and bring it back up again ?
