Hi All,

 

I have been getting the alert as below may i know if this is a kind of BUG ?

 

Ontap Version :- 8.2.3P5

 

Message: ses.multipath.ReqError: SAS disk shelf detected without a multipath
configuration.

Description: This message occurs when the system detects that a SAS disk shelf
is in a single-path cabling configuration.

Action: Check for SAS disk shelf enclosures with only a single path using the
'sasadmin expander_map' command. Physically inspect all SAS cables on the
attached storage for secure and correct connection.

 

Thanks, 

Nayab

Run config adviser (v 4). It's really good at telling you where you've got cabling problems.

 

Also I seen this on smaller systems with only 4 SAS ports and someone has decided to put different disk type shelves on separate loops as they traded resilience for possible performance.
