In the LUN Management section of the XP256 Remote Control software (in the "SCSI Path Parameter" window) it looks like I can define from LUN 0 up to LUN 77(octal). This means that I can define only 120 LUNs on a single port; the SCSI ID is fixed to "F" (on this window).
In the previous window ("LDEV Configuration - Without Shutdown") there is a "Free SCSI ID" section ranging from "0" to "E". How can I use these additional SCSI IDs to add more LUNs? Is it possible to define more than 120 LUNs on a single port of XP256?
Solved! Go to Solution.

I will try the LUSE ("Open Volume") feature of XP256 to consolidate the smaller LUNs into larger LUNs.

Re: Defining more than 120 LUNs on an XP256 disk array port
But raising the LUN sizes should prove helpful in my opinion, as it will shorten VG activation times.
I wouldn't put in switches if the host is direct attached now, because this will raise management overhead and risks of hardware/human failures.
Rather add two more HBAs, unless You see need for a SAN withhin the next two years or so.
(assuming You run securepath anyway *g*)
