Upgrade Dell PowerFlex to v3.6.x

Upgrading the driver

Upgrade the LSI RAID controller driver.

1. Upgrade the megaraid_sas 6.811.02 driver:

   rpm -Uvh /var/tmp/kmod-megaraid_sas-06.811.02.00_el7.2-2.x86_64.rpm

   NOTE:This installs the driver to the base kernel version for the relevant distribution/release.
2. Stop the SDS:

   /opt/emc/scaleio/sds/bin/delete_service.sh

3. Unload the driver:

   modprobe -r megaraid_sas

4. Copy the driver that you just installed to the base kernel version folder for your distribution/release, and overwrite the current driver file:

   cp
   /lib/modules/3.10.0-327.el7.x86_64/extra/megaraid_sas/megaraid_s
   as.ko /lib/modules/`uname
   -r`/kernel/drivers/scsi/megaraid/megaraid_sas.ko

   cp: overwrite
   "/lib/modules/3.10.0-327.4.5.el7.x86_64/kernel/drivers/scsi/mega
   raid/megaraid_sas.ko"?
   Y

5. Load the driver:

   modprobe megaraid_sas

6. Confirm that the just-installed driver is loaded:

   modinfo megaraid_sas |grep version
   

   version: 06.811.02.00
