Well, I finally stopped wasting time with it, and rebooted the server. The LUN appeared, and I have the new disk space. Sure would like to know how to do that without a reboot though - especially since other versions of RHEL could do it. Would hate to think that this isn't an option in RHEL5 :( -----Original Message----- From: Young, Mike Sent: Monday, April 16, 2007 10:18 PM To: 'General Red Hat Linux discussion list' Subject: RE: Detecting New SAN LUN in RHEL5 Plus, kudzu doesn't seem to do the trick.

Since RHEL5 doesn't require you to load the drivers of the vendor, none of the tools (lun_scan, et al) are installed either. There must be a way of detecting new LUNs without rebooting - everything else has been pretty automatic so far (card detection, activation, etc). > > -----Original Message----- > From: redhat-list-bounces@xxxxxxxxxx [mailto:redhat-list-bounces@xxxxxxxxxx] On Behalf Of Mark Haney > Sent: Monday, April 16, 2007 5:32 PM > To: General Red Hat Linux discussion list > Subject: Re: Detecting New SAN LUN in RHEL5 > > Young, Mike wrote: > >> Hello, >> >> What's the method for detecting newly allocated SAN LUNs in RHEL5?

I've not had a lot of success with doing it that way without rebooting. -- Mark Haney Sr. Systems Administrator ERC Broadband -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
