Use the show flogi command to verify if a storage device is displayed in the Fabric login (FLOGI). If the required device is displayed in the FLOGI table, the fabric login is successful.FDMI::show fdmi database / show fdmi database detail :Cisco MDS 9000 Family switches provide support for the Fabric-Device Management Interface (FDMI) functionality.FDMI enables management of devices such as Fibre Channel .Host Bus Adapters (HBAs) through in-band communications.Using the FDMI functionality, the SAN-OS software can extract the following management information about attached HBAs and host operating systems without installing proprietary host agents:Manufacturer, model, and serial numberNode name and node symbolic nameHardware, driver, and firmware versionsHost operating system (OS) name and version numberpacdcmdsa1# show fdmi databaseRegistered HBA List for VSAN 1 10:00:00:00:c9:5d:ee:ce 10:00:00:00:c9:61:1f:05 21:00:00:1b:32:13:64:ef 21:00:00:1b:32:82:0e:f4 21:00:00:1b:32:82:5b:f2 21:00:00:1b:32:82:66:db 21:00:00:1b:32:82:8d:f2 21:00:00:1b:32:82:8f:f5 pacdcmdsa1# show fdmi database detailRegistered HBA List for VSAN 1-------------------------------HBA-ID: 10:00:00:00:c9:5d:ee:ce-------------------------------Node Name :20:00:00:00:c9:5d:ee:ceManufacturer :Emulex CorporationSerial Num :BG65140697Hardware Ver :2057706dDriver Ver :6.10gROM Ver :1.50a8Firmware Ver :2.50A6 (Z2D2.50A6)OS Name/Ver :SunOS 5.10 Generic_127127-11CT Payload Len :525980Port-id: 10:00:00:00:c9 :5d:ee:ceSupported FC4 types :scsi-fcp fc-gsSupported Speed :1GCurrent Speed :2GMaximum Frame Size :2048OS Device Name :lpfcRSCN ::The Registered State Change Notification (RSCN) is a Fibre Channel service that informs hosts about changes in the fabric. Hosts can receive this information by registering with the fabric controller (through SCR). These notifications provide a timely indication of one or more of the following events:Disks joining or leaving the fabric.A name server registration change.A new zone enforcement.IP address change.Any other similar event that affects the operation of the host.switch# show rscn scr-table vsan 1SCR table for VSAN: 1---------------------------------------------FC-ID REGISTERED FOR--------------------------------------------0x1b0300 fabric detected rscnsTotal number of entries = 1FCS::The Fabric Configuration Server (FCS) provides discovery of topology attributes and maintains a repository of configuration information of fabric elements.
