HP-UX does not make it easy to keep track of SAN presented disks. HBA switch ports are in short supply in many data centers. It is important for performance and reliability to be able to account for how many disks are presented to what HBA WWN ports.<\/p>\n
This articles outlines a generic method of doing so. It is better than fcmsutil output but is based only on tools provided with the OS (with 1 small exception).<\/p>\n
To make sharing easier, I will provide links to scripts. It is up to you to perform due diligence. The scripts write no data and do not change your system. They are provided without warranty under US Law by ISN Corporation.<\/p>\n
I recommend against cutting and pasting scripts from this web page, errors are introduced. They are based on korn shell and do not work with bash shell. They probably work on POSIX shell but were not tested. They are specific to HP-UX B.11.31 but can if you wish be adapted to older versions of the OS.<\/p>\n
Links to scripts are at the bottom of the post which is quite long.<\/p>\n
Script names accurately describe their functionality
\nfcdisplaydev.ksh us a utility script designed to provide fcmsutil output to the other two scripts.<\/p>\n
