Cisco Cisco UCS C22 M3 Rack Server Manual Técnica

Update the SUSE Linux Enterprise System 11.3 kernel to version 

rr_min_io

flush_on_last_del

fast_io_fail_tmo

dev_loss_tmp

The resulting configuration file must look like this:

defaults {

user_friendly_names     no

}

devices {

        device {

               vendor                 "DGC"

               product                ".*"

               product_blacklist      "LUNZ"

               features               "0"

               hardware_handler       "1 emc"

               path_selector          "round-robin 0"

               path_grouping_policy   group_by_prio

               failback               immediate

               rr_weight              uniform

               no_path_retry          5

               

               path_checker           emc_clariion

               prio                   emc

               

 

       }

}

Note: The EMC white paper 

20, does not mention these changes because the white paper had been created before the
kernel bug was detected.
