Issue

  • Even after enabling BDFU with the disk option modify command, which would show BDFU state as "on" :
cluster::*> disk option show
Node      BKg. FW. Upd.  Auto Copy     Auto Assign    Auto Assign Policy
--------  -------------  ------------  -------------  ------------------
node-01      on             on            on             default
node-02      on             on            on             default
2 entries were displayed.
  •  The disk firmware Update state would show as "off" in the disk firmware show-update-status output:  

cluster::*> disk firmware show-update-status
                             Number     Average      Total
          Update   Waiting    Duration Completion
Node      State   Download /Disk (Sec) Est. (Min) Unable to Update
--------- ------- -------- ----------- ---------- --------------------
node-02   idle           0         120          0 -
node-01   off            2         120          4 -
2 entries were displayed.

  • An Update State of "off" would  be expected if the BDFU was suspended through raid options of the node, however, even after turning the suspend option on and then back off it wouldn't change to "idle":

cluster-02::> node run * options raid.bdfu

Node: node-01
raid.bdfu.suspend            off        (value might be overwritten in takeover)
raid.bdfu.suspend.time       60         (value might be overwritten in takeover)

  • As a result, the disk firmware updates on the remaining disks owned by node-01 could not complete.
