fcmsutil

[Waqar Razi]

Can some one explain me how to troubleshoot hba's with fcmsutil command? I am seeing the man page, but dont understand much.

Any help will be highly appreciated.

fcmsutil is handy to see the status of a HBA

It will tell whether it is initialised or not, link speed, hardware path, etc.

It will also tell you the driver state eg
Driver state = AWAITING_LINK_UP
or
Driver state = ONLINE

Take a looke at a known good hba first with fcmsutil for reference.

Below is the output of fcmsutil against an inactive hba and an active hba

Hi,

You can find the status of the HBA with the following commands.

fcmsutil
or
fcmsutil /dev/td0

where device file name you can find in ioscan output.

Detail statistics of the HBA you can find with the stat parameter with this command.

fcmsutil /dev/td0 stat

fcmsutil will tell you everything there is to know about the card. It cannot tell you anything about disks or tapes that are not showing up other than whether the link is up. If it is up, your next step is the SAN switch or the device.
