The driver version is 60660 from ftp qlogic, the kernel is a 2.4.20 and i have 2 fabrics ( switches ) and the 2 HBA are connected on each switch. The storage array system is an hsv110 with 2 ctrls. I have two path available for each hba. The driver was compiled with MPIO enable and the failover type is 5 ( #define FO_NOTIFY_TYPE_SPINUP 5 ) spine up ( scsi_cmd start ) because for changing port when a failure occur the failover driver must perform a scsi start on the second hba to force the unit to move on the next available port on which the second hba is connected. During test i unplug the fiber cable on the adapter and in the same time i make a tar and i copy files to the disk, the failover process seems to be ok and the unit goes to the other ctrl port no IO error occur but when i verify the tar i have some differences ( size ) and some files are incomplete, the copy seems to be ok, but if i compare the md5sum sometimes i have different md5sum. I have testing failover and failback the problem occur during the failover and failback. Do you have any idea for this problem ? I think a problem during the suspend lun or qla2x00_restart_queues but i'm not sure. For this time i continue test and i hope to undrestand this. I thank in advance for your help.
