I.3 Attaching the Disk Array
The simplest way to configure a disk array is to use System Administration Manager (SAM),
1.Use the ioscan command to determine what addresses are available on the HBA to which you will be attaching the array.
2.Access the firmware application on the array and set the SCSI IDs of the host channels you will be using.
3.Map the partitions containing storage that you want to use to the appropriate host channels.
Partitions must be assigned to LUNs in sequential order, beginning at LUN 0.
4.Halt the operating system using the shutdown command.
5.Turn off all power to peripheral devices and then to the server.
6.Attach one or more host channels of the FC or SATA array to the SCSI interface cards in the host using the supplied SCSI cables.
7.Turn on the power to the FC or SATA array and all other peripheral devices. After they are initialized, power on the server and boot
8.Verify that you can see the new storage resources by running the ioscan command. You are now ready to use the storage.
Note – If you create and map new partitions to the array, you can have them recognized by the operating system without rebooting. Run the ioscan and the insf commands to discover the resources and to create their device files.
