Hi Whenever I write some large file on SAN Logical Volume, after writing some data it gives me error in /var/log/message.
as follows:
Feb 28 11:08:53 s1_new kernel: cciss: cmd f7400000 timedout Feb 28 11:08:54 s1_new kernel: cciss: cmd f7436fb4 timedout Feb 28 11:08:54 s1_new kernel: printk: 232 messages suppressed. Feb 28 11:08:54 s1_new kernel: Buffer I/O error on device cciss/c0d0p9, logical block 2162845 Feb 28 11:08:54 s1_new kernel: lost page write due to I/O error on cciss/c0d0p9
Also it is noticed that when started with clean reboot of systems servers including SAN device) I/O on SAN works very fast for the first few seconds then it starts timeout and page lost errors
This is HP MSA 500G2 connected with HP DL 360 G4 , RHEL 4 ES U1(2.6.9-11) RHCS4
