Now I can't see the discs, running version 11.21 so assume I have to adjust some path related settings. It's a node in a cluster running veritas volume and service guard clustering.<BR /><BR />Any Sat, 02 Apr 2011 16:45:28 GMT https://community.hpe.com/t5/operating-system-hp-ux/changes-san-switches/m-p/4773044#M549288 Lars Janssen 2011-04-02T16:45:28Z https://community.hpe.com/t5/operating-system-hp-ux/changes-san-switches/m-p/4773045#M549289 The problem is more likely to be in the switches/cabling than HP-UX.<BR /><BR />Was the ZONING in the new switches verified?<BR /><BR />Was there a reboot or "ioscan -fnC disk" / insf -C disk <BR /><BR />fwiw,<BR />Hein<BR /> Sat, 02 Apr 2011 16:53:49 GMT https://community.hpe.com/t5/operating-system-hp-ux/changes-san-switches/m-p/4773045#M549289 Hein van den Heuvel 2011-04-02T16:53:49Z
