Compaq StorageWorks HSG60 ACS Solution V8.6 for SGI IRIX Installation and Configuration Guide

Preparing the Host System 3–5
5. If the devices have been correctly recognized by the operating system, they can be
labeled and partitioned. If the devices were not recognized, recheck the status of the
RAID Controller, logical units, and Fibre Channel connections.
6. If the RAID controller is properly configured and the optical cables are connected,
then use the following command sequence to re-initialize the loop and configure the
devices into Irix that are attached to controller #10:
# scsiha -r -p 10
# cd /hw
# ioconfig -f./
# hinv -v
If necessary, repeat the sequence for each host controller with Fibre Channel RAID
devices attached.
7. The logical units that were recognized by the operating system must be initialized
before they can be used for data storage. This initialization includes:
❏ Creating and writing the disk label
❏ Partitioning the storage
❏ Creating the file system, if required
Arbitrated Loop Device Name Convention
SGI Irix creates unique device names for devices attached to the Fibre Channel Arbitrated
Loop host adapters on the system. Understanding the device nomenclature will help in
providing device name-related answers in the following section.
Format used for LUN 0: dksxdysa
Format used for other LUNs: dksxdylzsa
NOTE: The “l” in the example is the letter “el”)
Where ...
x = controller (host Fibre Channel adapter) number assigned by host.
y = Loop ID in decimal
z = Logical Unit Number, LUN
a = Slice or partition number
The fourth slice (partition) on RAID Array logical unit D4 on Fibre Channel controller 10
