How to disable HBAs in HP-UX 11.23 servers ?

[Saravanan_6]

This is a question related to HBA's in Hp-UX servers. My HP-UX server 11.23 is attached with few HBAs. I want to make those HBAs not available in my HP-UX server without manually removing from the server. I want to disable HBAs without removing it from the server.

# ioscan -funC fc --- this command output should not show the actual HBAs present in the server.

Is there a way to do this ?

Hi,

what is the reason for this?

Of course you can power of the slots (but they will be powered after a reboot) or unloading the driver, but if you don't want to see devices behind the FC adapters, I would simply disable the ports on the connected FC switch.

Hi Saravanan,

instead of diabling the switchport you can
"fcmsuti(1m) disable" all the ports you don't need on the server.

But they remain in ioscan.

We can also use rad utility ???

Shalom,

1) Disconnect the fiber cable.
2) Have the unit removed by HP Hardware.

I am having few HBAs in my server and in next restart some HBAs should be disabled.. can we do it through EFI ??

thanks for all replies..


Please dont consider this part..
>>> start <<<
# ioscan -funC fc --- this command output should not show the actual HBAs present in the server.
>>> End <<<

3 HBA slots are filled with 3 HBAs and i am going to place a new HBA in another slot and the remaining HBAs should be disabled. ( without removing FC connections from HBA )..

Note : i was facing system booting problems with certain combinations of HBAs.

You can use "olrad" to switch the slot off as mentioned, but you can even open the lever on the slot directly to power it off.
