Configuring FAStT Storage for Failover and Multipath Visibility
Use the following guidelines to configure a FAStT Storage Processor and QLogic
controller so you can use HBA failover along with multipath SAN visibility and
Microsoft Cluster Services.
Be sure your FAStT is running firmware version 8.21. The firmware update is available
on the IBM Web site at http://www.pc.ibm.com/qtechinfo/MIGR-43752.html.
Be sure your FAStT has RST propagation and unassigned LUN claiming enabled. You
can enable these options by running a script developed by IBM. To do so, you should
be at the computer where you run IBM FAStT Storage Manager. Take these steps:
1. Copy the following lines and save them in a text file named
LinuxCluster.scr. Be sure you do not get extra line breaks in the file. They
may prevent the script from running correctly.
// Show Host Topology will show what Het Hosts
// are set for what OS
//show hosttopology;
// This is for sonoran code
// For Mojave use:
show controller[a] hostnvsrambyte[5,0];
show controller[a] hostnvsrambyte[5,1];
show controller[a] hostnvsrambyte[5,2];
// Byte 5,0 should be "L", 0x4c
// Byte 5,1 should be "N", 0x4e
// Byte 5,2 should be "X", 0x58
// Host Type definition INDEX of 5 should be for Linux
// Allow Reservations on unowned luns
set controller[a] HostNVSRAMByte[5,25]=1;
// Allow propagated host bus resets
set controller[a] HostNVSRAMByte[5,27]=1;
// Allow Reservations on unowned luns
set controller[b] HostNVSRAMByte[5,25]=1;
// Allow propagated host bus resets
set controller[b] HostNVSRAMByte[5,27]=1;
2. Using FAStT Storage Manager, look at Storage System > Profile and be sure that
Index 5 (DEFAULT) shows Name: Linux and ADT Status:
Enabled.
