Why Drive Status is SCAN-TLD if is not an SSO?

[Omar_Villa]

Have a couple of drives with scan-tld status is a nbu 6.0, never see this before in regular drive, no SSO is configured

3584E_L3-F1      No      No                     No        hcart2
   server /dev/rmt/1cbn                        SCAN-TLD
 
3584E_L3-F2       No      No                     No        hcart2
   server /dev/rmt/2cbn                        SCAN-TLD

Any idea?

Thanks.
