-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi! Let me please start with apology for using the development list to ask rather end-user question. I am looking for help with multipath setup. I have a few servers connected to a ibm storage. Two servers have two qlogic HBAs each. On the first server was created a multipath device out of all 4 scsi devices/paths. On the second server it is possible to assemble the same mp device and attach it without problems (there is the gfs). However, the third server I would like to connect to the storage has just one HBA. It's only 1U format and I cannot add anything to it. And moreover, the visible storage scsi device order there is different. As I know the mdadm that I used to create the multipath device writes to the superblock an information about the array, I would like to find out how much the multipath implementation in the kernel depends on this information. Would it be a problem to connect the third server to the storage by assembling the multipath device out of just two scsi devices/paths instead of four and in addition using scsi devices with diferrent minor/major numbers? As I do really doubt that, is there any way how to connect the third server using the multipath setup? Thank you very much for your help. I could get the answers by testing, but these are production servers with terrabytes of data and I cannot really stop them now for more then just a few minutes.
