More information
LUNs not recognized by DM-Multipath
LUNs are mapped to the Linux host and are correctly reported by the sanlun lun show all command. However, the LUNs are not reported by the multipath -ll command. Check to make sure the LUNs are not blacklisted (excluded) from the DM-Multipath support configuration in the /etc/multipath.conf file.
(FC) LUNs not visible on the Linux host
FC LUNs appear as local disks to the host. If the storage system LUNs are not available as disks on the hosts, try rescanning the HBAs by reloading the drivers. If the LUNs still do not appear, verify the configuration settings.
