Symptoms

Note: This article only applies for Gen 1 and Gen 2 ECS nodes. Those nodes have a SATADOM drive that has the boot partition. When this Drive Fails, the node does not come back if it ever goes through a reboot.

Example of this issue from xDoctor: 
 Timestamp    = 2016-05-12_140748
    Category = Health
    Source   = Disk
    Severity = ERROR
    Node     = 169.2XX.1.2
    Message  = Boot device is not accessible
    Extra    = /dev/sda
    RAP      = RAP004
    Solution = 463067

Cause

If the boot device is not accessible, most likely the SATADOM (Boot) disk has issues.

Resolution

If xDoctor reports this issue, open a service request with Dell Support and reference this article.
(In this case, the SATADOM disk per the xDoctor output is /dev/sda, in other situations it may be /dev/sdb)

Also, grab the output from the following command and place it in the service request:

Command:

# sudo /opt/emc/sbin/iSMART_64 -d /dev/sda
