HBA

I need few details on HBA cards,
In Hp-UX to check the HBA card installed we can use
#ioscan -fnC fc
#fcmsutil /dev/fcd0

Please correct me if i am wrong.
Experts please let me know to check if HBA card has failed to detect. Troubleshooting steps that can be done from host.

Re: HBA

Talking about fibre adapters only?

Where exactly is the problem?

>> failed to detect

No driver loaded?
Do you see any "UNKNOWN" in ioscan?

Hope this helps!

Re: HBA

Hi

You collect part and model and versions. Model and version of your box and server.

For HBA part number use
fcmsutil /dev/fc## vpd

..unless /dev/td, or tacheyon, then

swlist -l product | grep -i tach

"...failed to detect..."

Check the state / status parameter in fcmsutil

fcmsutil /dev/fc##

It will either be online or not. Online is good.

Re: HBA

Hi again

Trouble shooting steps. Usually the online confirmation is enough. You can send a echo back to the SAN to verify connectivity but this is intrusive and can only be done when the disk array is down, or something to this affect. The point is, it is intrusive and destructive.

So, trouble shooting is now by log tool, which is an error collector.

cstm<<-EOF
runutil logtool
rs
EOF

Copy and paste in and I'll go over it with you. Note: Get the start and end dates.

Re: HBA

Hi Sarwan/Jijesh..

>> If it is not listed in ioscan.
Depends on the state in ioscan.
-Not listed in ioscan might indicate HW issue.
-Present but UNCLAIMED state might refer to driver issue.

You can use following commands also to troubleshoot HBAs.
# fcmsutil /dev/td0 stat -s
# what /stand/vmunix | grep -i td <<< Check for drivers in kernel

Re: HBA

HI


If the card is listed in ioscan , you can use
ioscan -fnC fc
then for the device files that you get that is /dev/fcd0 or /dev/td0 or /dev/fclp0 you can use to see the Status of the card using

fcmsutil /dev/fcdX
fcmsutil /dev/tdX
etc
