The globalSAN initiator is simply a connection mechanism. Once the disk is connected, Mac OS will recognize a filesystem and mount that filesystem at /Volumes/FilesystemName. If that is not happening, then either globalSAN is not actually making the connection, or else the filesystem isn't being recognized and therefore is not being mounted.
Typically, our customers are using SANmp as well as globalSAN. In that case, the volumes are only mounted when the user directs SANmp to mount them. If no SAN management software is in use, the OS should mount the volumes automatically. However, if more than one workstation attempts to connect at the same time, they would both have write access, which would corrupt the volume.
Are you using any SAN management software?
