One client uses IBM system x3650 server, which is mounted S2600S storage. The system of the server is centos 5.2, single-link. Then the server cannot find the mapped LUN.
Add a SAS HBA card for the server, which is connected for S2600S. It can recognize the mapped lun after rebooting.
IBM system x3650 server is integrated with Adapter SAS HBA card, a SAS port outside, which connects S2600S. This port is mainly used for IBM SAS array, which is not compatible with storage of our company.
We suggest to use 25R8060(LSI company).
