checking fc connectivity

[Ahmed Douban]

hi experts

i want to know if there is any command/tools can be used to determine if server fc is connected or not

actually i tried to use

# ioscan -P health -C fc
this command reports fc port status but no reporting about if it connected or not

thanks

Considering the wide variety of options that your fiber interfaces can connect to, it is very hard to write such a utility.

ioscan utility is there to scan the buses of hpux server to report the hardware attached to the system. You will need a utility from your FC attached fabric or device manufacturer to tell you if there are any devices connected to your WWN. There is no generic form of this utility, although the system monitoring platforms, likes of HP Open View and such, have an extensive library of FC equipment, which they can check to see if any such device is connected. But writing such a utility, especially for public domain, is a big undertaking, which I would not be willing to do.

I assume if your command show the storage device is healthy, this means it is connected (what else?).


However, fcmcutil will show you the connection status HBA <-> switch.

@mel hp openview is old name right now and contain alot of products so may you till me witch HP software product


@Torsten
it seems you mean this command
#fcmsutil

may you please provide a more details to run this command to test connectivity between HBA <--> san switch or FA (WWPN) of storage

thanks guys

[Torsten. · Accepted solution]

From ioscan get the device file (e.g. /dev/fcd0) and run

# fcmsutil /dev/fcd0

and you get among other details the WWN of the HBA, WWN of switch port, connection status and speed.

perfect mate

it works

here is the output

only the first FC is connected the second output of FC2 not initialized

thanks again

u can also use

fcmsutil /dev/fcd0 'vpd' to get details of hba
