Hi list, CentOS 4.4 connecting to Promise M500i iSCSI disk array. 2/4 servers connect fine with iscsi-initiator-utils-4.0.3.0-4. The other 2 servers have this in dmesg: SCSI device sdb: 1 512-byte hdwr sectors (0 MB) sdb: asking for cache data failed sdb: assuming drive cache: write through SCSI device sdb: 1 512-byte hdwr sectors (0 MB) sdb: asking for cache data failed sdb: assuming drive cache: write through sdb:<6>Device sdb not ready. end_request: I/O error, dev sdb, sector 0 Buffer I/O error on device sdb, logical block 0 Device sdb not ready. end_request: I/O error, dev sdb, sector 0 Buffer I/O error on device sdb, logical block 0 Device sdb not ready. end_request: I/O error, dev sdb, sector 0 Buffer I/O error on device sdb, logical block 0 Attached scsi disk sdb at scsi1, channel 0, id 0, lun 0 The drive does not allow connections after this failed attempt at guessing the write cache type. Is there a way to hard-code the write cache setting on the server? Anyone experience this with other hardware/iscsi/promise devices?
