Sun Proprietary/Confidential: Internal Use Only
Verifying the Data Host
An error in the A2 or B2 FC link can result in a device being listed as in an
“unusable” state in
cfgadm , but no HBAs being listed in the “unconnected” state in
the luxadm output. The multipathing software will note an offline path, as shown in
CODE EXAMPLE 5-4 .
CODE EXAMPLE 5-4 cfgadm -al
Note – You can find procedures for restoring virtualization engine settings in the
Sun StorEdge 3900 and 6900 Series 2.0 Reference and Service Guide.
