Hi;
Workaround is found.
The linsysfs create directories /compat/linux/sys/class/scsi_host/host*
for each device of class PCIC_STORAGE by default.
I has changed this behaviour and resolved my problem by this patch:

/* DJA only make this if needed */
sprintf(host, "host%d", host_number++);
strcat(new_path, "/");

With this patch linsysfs created directories
/compat/linux/sys/class/scsi_host/host* for RAID controllers only and
not created for SCSI controllers like mpt. The RAID controller mfi0
detected so as /compat/linux/sys/class/scsi_host/host0 in linsysfs and
linux-megacli works correctly.
The topic is closed. Thanks.
