U mean stk 2540? Iirc one can download drivers from oracle sun site ------- Original message -------From: David Noriega <[email protected]> To: [email protected] Sent: 13.8.'10, 11:51 We have three Sun StorageTek 2150, one connected to the metadata server and two crossconnected to the two data storage nodes. They are connected via fiber using the qla2xxx driver that comes with CentOS 5.5. The multipath daemon has the following config: defaults { udev_dir /dev polling_interval 10 selector "round-robin 0" path_grouping_policy multibus getuid_callout "/sbin/scsi_id -g -u -s /block/%n" prio_callout "/sbin/mpath_prio_rdac /dev/%n" path_checker rdac rr_min_io 100 max_fds 8192 rr_weight priorities failback immediate no_path_retry fail user_friendly_names yes } Comment out from multipath.conf file: blacklist { devnode "*" } On Fri, Aug 13, 2010 at 4:31 AM, Wojciech Turek <[email protected]> wrote:Hi David,I have seen simmilar errors given out by some storage arrays. There were caused by arrays exporting volumes via more then a single path without multipath driver installed or configured properly. Some times the arraycontrollers requires a special driver to be installed on Linux host (for example RDAC mpp driver) to properly present and handle configured volumesin the OS. What sort of disk raid array are you using?
