Instructions


NOTE: You need physical access to the node in order to complete the power drain.

Procedure Gen 5

STEP 2. Power-off the node.

#  isi_flush
       and wait for the flush to complete.
Then run 
#  shutdown -p now
     to shut down node  

Visually verify that all lights on the node have turned off.

NOTE: Sometimes this commands fails to power down the node. On occasions, it will reboot the node instead or simply fail to work. In those situations, follow the next options in order until the node is fully powered-down and remains off.

*** If node successfully powers off, go to STEP 3.

If shutdown command does NOT power down the node, but reboots it instead, wait for the node to finish booting, then run the command again - it should shut down properly. If it does not, or if the command did not reboot the node either, please contact EMC-Isilon Technical Support.

STEP 3. Once the node is powered off, to fully power drain the node and reset the BMC, for gen 4 and 5 remove both power cords, then wait 3 minutes and hold the power button for 30 seconds. 

STEP 4. Reinsert the power cords

STEP 5. Restart the node by pressing the power button on the back of the node. 

If the node does not power back on, or if it fails to boot successfully, please collect boot logs and contact EMC-Isilon Support.

Then run 
#  shutdown -p now
     to shut down the node.  

STEP 2 Log into IDRAC and confirm that node is powered down though vConsole.

STEP 3 In IDRAC go to Configuration -> BIOS Settings.
  • Under Miscellaneous Settings: Change Power Cycle Request to "Full Power Cycle" and Apply.
change Power Cycle Request Under Miscellaneous Settings

If the host is ready to reboot, go ahead and initiate by "Apply and Reboot." Else the user can save this for a manual reboot using "At Next Reboot"

Option 2: Boot into BIOS Settings
