Monitoring Fiber Channel Traffic to Array Mounted Disks

We have several servers (K570's N400's L200's) which are fiber channel connected to disks on an XP256.

Some of the servers are single channel connected, others are dual channel connected.

Are there any tools like glance which we can use to monitor the level of traffic moving across the fiber ?

Re: Monitoring Fiber Channel Traffic to Array Mounted Disks

The script I am attaching monitors by disk. As far as I know there is no utility to monitor the fiber because the OS really doesn't "own" the fiber.

To the OS, its just another SCSI device.

We have " tdutil" which is fcmsutil for td driver only. get the
ioscan -fnC fc and find the /dev/tdX of your system then
tdutil /dev/tdX stat (device statistics)
tdutil /dev/tdX devstat all
tdutil /dev/tdX csstat all
tdutil /dev/tdX nsstat
