Error: FCP driver not loaded. failure in ioctl: Invalid argument

[Ravi S. Banda]

I'm having a problem when doing a "fcmsutil /dev/td0".

Could you tell me what I need to do.

ls -l /dev/td0
shows:

crw-rw-rw- 1 bin bin 49 0x000000 Dec 30 12:30 /dev/td0

lsdev shows:
Character Block Driver Class
48 -1 fcp fcp
49 -1 td fc

What do I need to do?

fcmsutil /dev/td0 shows:

Error: FCP driver not loaded.
failure in ioctl: Invalid argument

This is essential as I have created Virtual disks from the SAN, but they don't show up as LUNs on the server. The driver was the right one for the HBA:

A6795A B.11.00.10 PCI Tachyon TL/TS/XL2 Fibre Channel

Thanks!
Ravi.

Does ioscan show the hardware and are you sure it's /dev/td0?

# ioscan -fnCfc


Also, does tdlist or fcdlist show anything?

ioscan -fnCfc shows:

Class I H/W Path Driver S/W State H/W Type Description
=================================================================
fc 0 0/5/0/0 td CLAIMED INTERFACE HP Tachyon XL2 Fibre Channel Mass Storage Adapter

tdlist came back with nothing.
fcdlist not found.

Thanks!

Hi,

It seems that fibre channel protocol ( FCP ) is not enabled. The FCP uses FCMS driver.
This card requires td and fcms drivers.

Check the version of FCMS driver installed in the system using
(Assuing the system booted )using "/stand/vmunix"
# what /stand/vmunix | grep fcms
# what /stand/vmunix | grep td

Have you installed the required patches for this card? I see the td driver is latest.
check for FCMS driver at
http://www2.itrc.hp.com/service/patch/mainPage.do

If the FCP is enabled you should see an entry in the "ioscan" just below the entry of the adapter.
fcp 2 0/4/0/0.1 fcp CLAIMED INTERFACE FCP Domain

Moreover, depending on which server it is being installed , you need to upgrade the its PDC firmware as well.

I applied all the patches/patchsets that were required for FibreChannelMS and that took care of the problem.

Thanks!
Ravi.
