Upgrade Dell PowerFlex to v3.6.x

Upgrading the firmware

Upgrade the LSI RAID controller firmware.

1. Pull and record the current controller configuration:

   storcli /c0 show all

   Note the current firmware and driver versions shown in the output (similar to the following example):

   Version :
   =======
   Firmware Package Build = 24.7.0-0026
   Firmware Version = 4.270.00-3972
   Bios Version = 6.22.03.0_4.16.08.00_0x060B0200
   NVDATA Version = 3.1411.00-0009
   Ctrl-R Version = 5.08-0006
   Preboot CLI Version = 01.07-05:#%0000
   Boot Block Version = 3.06.00.00-0001
   Driver Name = megaraid_sas
   Driver Version = 06.807.10.00-rh1

2. Disable CacheCade and flush all cached data to disk:

   storcli /c0 /vall set ssdcaching=off

   NOTE:This command will fail for SSDs. As it only applies to HDDs, this is expected behavior, and is not a problem.
3. Allow time for the cached data to write completely to disk. When this is done, VDs will show "-" in the Cac column of storcli /c0 show output. Once the Cac column value shows as "-" for all VDs, proceed to the next step.
   Typical output:
   

   

   
   
4. Delete the CacheCade VD:
   NOTE:Do not delete the CacheCade device until all cached data has been written to disk. Otherwise, data loss could occur.

   storcli /c0 /v0 del cc

5. Enable booting with pinned cache:

   storcli /c0 set bootwithpinnedcache=on

6. Upgrade the controller firmware:

   storcli /c0 download file=/tmp/mr3108fw.rom

7. Restart the host to apply the firmware change:
   1. Restart the host.
      NOTE:This restart will apply all of the driver and firmware upgrades.
   2. Confirm that the controller firmware and driver have been updated to the target version:

      storcli /c0 show all | grep "Firmware Package Build\|Driver
      Name\|Driver Version"

      Output similar to the following should be displayed:

      Firmware Package Build = 24.15.0-0016
      Driver Name = lsi-mr3 (Megaraid_sas on Linux)
      Driver Version = 6.611.05.00 (6.811.02 on Linux)

8. Recreate the CacheCade device, then set its rdcache parameter:
   1. Type the command:

      storcli /c0 add vd cc type=raid0 drives=E:0-1 wb

   2. Obtain the new VD ID in the Name column, in the row corresponding to the Cac0 type volume, using the command:

      storcli /c0 show all

      This step is required because the VD ID may have changed as a result of the upgrade.
   3. Type the command:

      storcli /c0 /v<x> set rdcache=nora

      where <x> represents the VD ID obtained in the previous step.
      For example, if the VD ID in the Name column is VD1, type the following:

      storcli /c0 add vd cc type=raid0 drives=E:0-1 wb
      storcli /c0 /v1 set rdcache=nora

9. Activate CacheCade for the HDDs:

   storcli /c0 /vall set ssdcaching=on
