Dissecting the SFA log of failed drive info

Scope

This article applies to DDN SFA 12K, 10K, 7700 and 6620 line of storage systems.

Description

The log output example below are in its original chronological order but it is broken up into sections for clarify.  Some extraneous info were removed to further enhance readability.

The entire unmodified output is available at the bottom as a .txt download.

This example has a failed drive, spare drive pool and auto reassign enabled.

Note

There is no way to capture the serial number of the failed disk from the log if the log is captured after the drive had failed.  If there is access to a previous log then you can use the ID (ID:0x5000cca057470dd8 in this example) of the drive and search from a previous log to get the drive's serial number.
