Symptoms

Exachk script for Engineered Systems (script version 12.1.0.2.6), has a new feature which checks the "Life Expectancy" of the internal SSD-drive in the NM2 GW & 36p Switches.   Example output may show:

 


Unfortunately, two regression problems have been found with this new feature:

 

1.  The current threshold is too high (10%).   So as to align with the corresponding ASR alert, this will be re-calibrated to 2% in a future release of Exachk.  


2.  If the IB Switch firmware is lower than 2.1.x, the script may report a false-negative (since the IB Switch "showdisk" command does not exist in the earlier releases)

 

The internal SSD drive inside the IB Switch can only be replaced by swapping the IB Switch itself.   Replacing the IB Switch too early, represents additional inconvenience for the customer.

 

Changes

Changes in the environment may include that Exachk version 12.1.0.2.6 has recently been installed
