Exactly. Mike seemed to be on to this path in February: https://www.redhat.com/archives/linux-cluster/2007-February/msg00178.htm l The Xyratex StorView software should be able to help you LUN Mask/Map so that each blade sees only its own LUNs. As long as each of your blades have unique WWNs. ? > -----Original Message----- > From: linux-cluster-bounces@xxxxxxxxxx > [mailto:linux-cluster-bounces@xxxxxxxxxx] On Behalf Of Michael Will > Sent: Thursday, March 15, 2007 12:42 PM > To: isplist@xxxxxxxxxxxx; linux clustering; > anaconda-devel-list@xxxxxxxxxx; redhat-install-list@xxxxxxxxxx > Subject: RE: Custom Anaconda to see 32 LUNS? > > How does a blade know to boot from a specific lun? > > Can you do a LUN-SAN mapping that would make a lun available > to only one specific blade each under the correct name? > > > Michael > -----Original Message----- > From: linux-cluster-bounces@xxxxxxxxxx > [mailto:linux-cluster-bounces@xxxxxxxxxx] On Behalf Of > isplist@xxxxxxxxxxxx > Sent: Thursday, March 15, 2007 11:13 AM > To: linux-cluster; anaconda-devel-list@xxxxxxxxxx; > redhat-install-list@xxxxxxxxxx > Subject: Custom Anaconda to see 32 LUNS? > > Is there anyone out there who might have a custom anaconda > version which could see at least 32 LUNS or more? > > I have yet to find a way of installing blades onto 32 volumes > which are on a fibre channel storage device.
