Solution Type Technical Instruction Sure Solution 1007820.1 : How to: Methods to set the SCSI Initiator ID at a specific PCI slot of E450 in Sun[TM] Cluster environment
PreviouslyPublishedAs 210811 Description In a cluster with dual-hosted SCSI storage, it is necessary to change the SCSI Initiator ID on the HBA (Host Bus Adaptor - the SCSI adaptor) on one node. The simplest way to make a change globally is to set scsi-initiator-id at the Open Boot PROM environment. However the E450 is an exception; the setting does not apply to Host Bus Adapters at all slots. This document provides a list of PCI slots that this OBP applies to and gives a reference explaining how to set the SCSI Initiator ID on HBA cards in other slots. Steps to Follow The E450 OpenBoot[TM] PROM (OBP) code creates changes to PCI nodes in /pci@1f,4000 and pci@1f,2000, that is the changes apply to the internal SCSI bus and Host Bus Adapter at PCI slots 10 and 5 respectively. To set the SCSI Initiator ID of the HBA in other PCI slots, you need to create or nvedit the nvramrc script. The following table lists the necessary method to configure a HBA in a specific PCI slot of E450. Slot# Device Tree Effect of setenv scsi-initiator-id in OBP ---- ---------- -------------------------------- 10 /pci@1f,4000/scsi@4 SCSI Initiator ID changed 9 /pci@4,4000/scsi@2 no effect, need to use nvedit 8 /pci@4,4000/scsi@3 no effect, need to use nvedit 7 /pci@4,4000/scsi@4 no effect, need to use nvedit 6 /pci@4,2000/scsi@1 no effect, need to use nvedit 5 /pci@1f,2000/scsi@1 SCSI Initiator ID changed 4 /pci@6,2000/scsi@1 no effect, need to use nvedit 3 /pci@6,4000/scsi@2 no effect, need to use nvedit 2 /pci@6,4000/scsi@3 no effect, need to use nvedit 1 /pci@6,4000/scsi@4 no effect, need to use nvedit For more detail usage of nvedit, refer to Technical Instruction <Document: 1007430.1> Product Sun Enterprise 450 Server Sun Cluster 2.2 7/00 (SC2.2 U2) Sun Cluster 3.0 Internal Comments Contact Ka-Yue.Chan@sun with questions or comments.
