Re: Mounting iscsi devices with sles 11

I am not sure abpout sles11, but you need a patch (which was posted to Novell a few times) to do it @ sles10 sp2. 

I put it here, just in case:

##echo "patching iSCSI:- change LVM to watch out /dev/disk/by-id and wait for the multipath- rescan LVM groups when iscsi login to the targets- mount 'hotplug' devices when lvm find new volumesEdit /etc/lvm/lvm.conf manually if you dont wang lvm changes. Open-iscsi patch is harmless and can be applied in ALL casesDon't forget to add hotplug option to the iSCSI disks and TEST system reboot few timesINCLUDING reboot with 1 iscsi paths down."mv /etc/lvm/lvm.conf /etc/lvm/lvm.conf-ORIG; cp FILES.d/lvm.conf /etc/lvm/lvm.conf## Now patch open-iscsi if it was not pached already#grep lvm /etc/init.d/open-iscsi || patch /etc/init.d/open-iscsi < FILES.d/open-iscsi.patch## Now move all orig and reject files out of /etc/init.d because it can confuse # the system elsewhere#if [ -f /etc/init.d/open-iscsi.orig ]thenmkdir -p /etc/init.d/OLD; mv /etc/init.d/*orig /etc/init.d/*.rej /etc/init.d/OLDecho "Please check how open-iscsi was patched - patch failed.Old files are at /etc/init.d/OLD"fiif [ ! -f /etc/multipath.conf ]then    cp FILES.d/multipath.conf /etc/multipath.conffi## Now enable #chkconfig open-iscsi onchkconfig boot.lvm onchkconfig multipathd onAnd then

iscsi.patch:

Don't ask me why SuSe team can't make so simple thing for the 2 years (already) and adjust all 3 components - iscsi, lvm, multipath - properly so that they wil work _out of the box_ (as in RHEL for example).
