TGT with DRBD for iSCSI replicated SAN

When I run this command:  iscsi -ls -l

 

I get the following output.

 

My setup is running just fine, but I am wondering what this message  in the output below means:

 

"0:0:0:X: expected length 24, got length 20"

 

I'm running iscsi-initiator-utils-4.0.3.0-10

 

TIA!

Re: TGT with DRBD for iSCSI replicated SAN

It looks like it has something to do with the number of characters (e.g. wc -c) returned in the "page83" field but I'm not sure of that. Apparently it is expecting the LUN name returned to have 24 characters but is getting only 20?
