I have an Intel Multiflex system MFSYS25 with six blades and an Promise vTrak e310s.
4 of the servers have internal storage presented but i want that the other two servers to boot from Promise and use a shared lun. I followed the instructions in the connection guide from intel but when i'm trying to boot the second server, the first one freezes and cannot access the storage.
What is strange, is that even i don;t have any internal storage presented to the servers, in the LSI sas from the blade i see a lun 0 Multiflex V-LUN. How can i disable it?
I have to mention that i use RedHat Enterprise Linux 6.5 on the servers.
I don't think you can use Shared LUN on an external drive. the FAQ at

Can a Shared LUN be used with external devices?
A Shared LUN can only be used with virtual drives within the chassis.
I use a Promise VTrack e310s with vmware. All my luns on the vtrak are shared ones, no problem here. However you have to make sure the LUNS on the vtrak are NOT called Lun0, I read somewhere on the net that this causes troubles. vmware still calls the first lun lun0, no matter what number you give on the vtrak. However I am not sure if you will be able to boot your servers.
