According to the IMT it looks as though FC isn't a supported protocol under SMO and RH/OL 6.x. Is there anyway to find out when or if FC will ever be supported with SMO+RHEL/OL 6.x? dNFS on Oracle 11G seems as the way to go though haven't had much buy in from seasoned DBA's.
Re: SMO Unknown block device handler "device-mapper" for device
All of the commands below work except for "sanlun fcp show adapter all" and this results in an immediate segfault.
sanlun lun show
sanlun lun show -p
sanlun fcp show adapter all
snapdrive storage show -all
snapdrive storage show -dev
To give a little more background we're trying to we're trying to run all this on Cisco UCS B200 M2 servers and the M81KR virtual interface card. To get this hardware to work with SnapDrive I ended up patching libhbalinux to recognize the HBAs correctly. Unfortunately the patch resulted in a segfault when running the "sanlun fcp show adapter all" command though every other snapdrive command worked successfully. I've attached the patch to this post as it doesn't look like issue had been addressed in the current lport.c source.
To answer your question about providing a re-scan script this was never done. The only reference to /root/dynamic-lun-rescan.sh that I was able to find was in the SDU 4.1.1 Installation and Administration Guide for Solaris.
