fcmsutil /dev/fcms1 hangs server

[kenny chia]

Hi
I ran the following command on my HP-UX 10.20 server
# fcmsutil /dev/fcms1

The server hanged after the command is issued. Does anyone face this problem before? Below is the ioscan for fcms1

Hi
I realised that the man page for fcmsutil states that the command is to be used on a certain adapters only

*----------------------------
DESCRIPTION
The fcmsutil command is a diagnostic tool to be used for the A3591A,
A3404A, and A3636A Fibre Channel Host Bus Adapters. This command
provides the ability to perform Fibre Channel Test and Echo
functionality, provides the ability to read the card's registers, etc.
This command requires the use of a device file to indicate the
interface over which the requested command needs to be performed.
fcmsutil can be used only by users who have an effective user ID of 0.
Some of the options require detailed knowledge of the device specific
adapter.
*---------------------------

Are there any kind souls who will dare to try the fcmsutil command on other devices (eg tape drive) and see if it hangs the server?
10 points for test results !!!
