IScSI target
The iSCSI SAN protocol sends and receives SCSI commands over
IP networks, making remote data storage facilities appear as local
disks. Servers running iSCSI initiator software can use the DataGuard
Appliance to access disk volumes. Use the iSCSI settings menu to
configure these services.
Every Imation DataGuard Appliance supports use of iSCSI, functioning
as a target or initiator. The R4 and T5R both support iSCSI boot
service. The iSCSI features can be used with DHCP service and PXE to
provide full-service boot up for properly equipped clients.
• Use the iSCSI Node Settings menu to configure iSCSI node
(target) function.
• To configure iSCSI network booting, go to Administration >
Service > iSCSI Boot Service.
• To configure LUN Mapping, go to Storage > LUNMap.
• To configure the DataGuard Appliance to function as an initiator,
go to NAS > iSCSI Initiator.
• From the Storage tab, click iSCSI Target to display the iSCSI
(Internet Small Computer System Interface) information in the
system and configure iSCSI settings.
