Manually Releasing SED Disks

Problem:

Unable to access SED disks after a reformat or reimage, error similar to "Unable to release ownership of "da1", result "Drive authorization failure""

Conditions:

SED disks will need to be manually released
You will need the PSID number off each individual disk
A putty connection for the bash shell to release disks manually

Solution:

  1. Power off the problem node
  2. Carefully remove all drives associated with that node, be mindful that the drives go back in the same position they were removed
  3. Capture (preferably with a picture) the PSID found on the label on each drive
    ../../Work/Images/EMC/Isilon/psid.png
  4. Once the boot process of the node reaches an option menu, press key combo "ctrl+c" to drop to bash. Most of the time you will need to press "enter" to confirm
  5. From the bash prompt "#" start manually releasing SED disks
/usr/bin/isi_hwtools/isi_sed_batch revert

Note: If this command fails to complete, we can run the command one bay at a time
/usr/bin/isi_hwtools/isi_sed revert <bay#>
bay0 is the SSD, disk A0 starts at bay3
Bays are ordered from top to bottom A - E and 0 - 2.
