Before I go off and re-invent the wheel, was wondering if anyone hasdeveloped an ext module for checking performance on fiber HBA cards on HPUX platforms. Still trying to figure out what all would be of interest besides the I/O rate (how close to saturating the PCI bus backplane). Checked on deadcat and searching with various buzz words did not find anything of interest. Figure would be generating a list of fiber devices (Tachyons in particular) and feeding them through tdutil command with "devstat all" arguments. HP support recommended using tddiag which can be overkill even with some of the options specified. I know there are some ext modules for monitoring performance on the fiber switches. I was monitoring on Brocade switches but we have switched over to Cisco switches and I no longer have access to the switches. I also want to monitor health at the PCI backplane to HBA card interface.
