Replacing LUN's
The standard was 36 GB now it is 100GB. When a new LUN is assigned if it is a new LUN trunk it appears as 100GB but if it is replacing one of the 36GB LUNs that have been removed the Host can only find 36GB while the SAN finds 100GB. How can I force the HPUX 11.2 & 11.3 hosts to see the full 100GB? I know I a few years ago when I moved from 8GB to 36GB I used a command that forced the host to see any disk replacement as a new disk and read the disk/LUN I just don't remember how to do it anymore. Does anybody know how to accomplish this other than the work around of creating multiple smaller LUNS to replace the old 36GB LUNs forcing the new LUNS to attach to a virgin trunk?

Re: Replacing LUN's
For replacing a LUN with a new one you can use the "scsi_mgr replace_wwid" command.
