DVS_READY and DVS_UNOPENED

Question

Could some one explain DVS_READY and DVS_UNOPENED?

root [/root] /opt/fc/bin/fcmsutil /dev/td0 get remote all

Target N_Port_id is = 0x615e13
Target state = DVS_READY
Target Port World Wide Name = 0x5006016030603525
Target Node World Wide Name = 0x50060160b0603525

Santhosh it looks like this is something you can ask to your HP sales rep docs.hp.com/en/A6826-96009/ch01s08.htmlUnfortunatly I can't read the page, but it looks like a promising result.

that is about just interpretting the LUN h/w path.

I think that you have to ask HP .. since you pasted the output of an hpux command .. and only HP can explain you what the hell it is saying

However let's see if someone can find better answers to your thread.

From my experience the DVS_READY means that the storage device allow initiator logins on the port; DVS_UNOPENED may appear in cases where the WWN of the hba is not registered on a Clariion Array or when a DMX storage port (VCM Enabled) is accesible but no device was masked for that particular port or even in cases where a storage port was moved in SAN from one port-id to another so the host does not authenticate it anymore.
Generally, it means that something is happening with that device but this may only be interpreted on an active device: if the host does not try to acces luns on that specific storage it may be possible that the state of the device to be unopened.
I guess that this state means that the host did not tried to open (login in fabric terms) the devi ce in the last period of time (AFAIK the hp-ux logins to the device each time it opens it) or tried and failed.
Hope that this helps.
