What determines this limit? Are there any kernel parameters needed to be modified to reach this limit? Is this maximum greater with HP-UX 11i?<BR /><BR />The XP512 can now go to 4096 LDEVs, but I don't believe the OS can support that many LUNs. Does anyone have a situation where they are configuring more than a thousand LUNs on HP-UX?<BR /><BR /> Thu, 08 Mar 2001 14:03:57 GMT https://community.hpe.com/t5/operating-system-hp-ux/maximum-lun-count/m-p/2502867#M21149 Q Seleca 2001-03-08T14:03:57Z https://community.hpe.com/t5/operating-system-hp-ux/maximum-lun-count/m-p/2502868#M21150 Just bring this question back from the dead..<BR /><BR />There should be no problem to the OS.<BR />The problem will be at CPU/adaptor level!!<BR />Well, By default there is a maxpv of 16<BR />set by kernel parms and a max number of<BR />vg's=255.. that's by default.<BR />The maxpvs should increase to 255 in a vg.<BR />So that's quite a lot... 65k PVs<BR />That should be enough!<BR /><BR />Later,<BR />Bill Thu, 15 Mar 2001 15:12:51 GMT https://community.hpe.com/t5/operating-system-hp-ux/maximum-lun-count/m-p/2502868#M21150 Bill McNAMARA_1 2001-03-15T15:12:51Z
