1. When a SLES 11 1 host with smartd monitoring enabled is mapped to volumes on either a Sun Storage 2500 M2 or 6780 array it is possible to receive IO FAILURE and Illegal Request ASC ASCQ log events Workaround Either disable smartd monitoring or disregard the messages This is an issue with the host OS Cluster Startup Fails When Devices Are in a Unit Attention State Configuration m Red Hat Enterprise Linux RHEL version 6 0 with Native Cluster m Device Mapper Multipath DMMP failover driver Problem or Restriction This problem occurs when the DMMP failover driver is used with the RHEL version 6 0 OS If you try to set up a Red Hat cluster with the DMMP failover driver cluster startup might fail during the unfencing stage where each host registers itself with the SCSI devices The devices are in a Unit Attention state which causes the SCSI registration command issued by the host during startup to fail When the cluster manager cman service starts the logs show that the nodes failed to unfence themselves which causes the cluster startup to fail Workaround To avoid this problem do not use the DMMP failover driver with RHEL version 6 0 To recover from this problem open a terminal window and run sg turs n 5 device where device is a SCSI device that is virtualized by the DMMP failover driver Run this command on every dev sd device that the DMMP failover driver manages It issues a Test Unit Ready comman2.
