A6826A PCI-X Host Bus Adapter for Linux 64-bit Systems Installation Guide
System Driver Parameter max_scsi_luns
Support for multiple LUNs can be configured in one of three ways. Currently, the
maximum number of LUNs that can be scanned for each device is 128.
Note:
If you have multiple HBAs, set max_scsi_luns to the largest number of LUNs
supported by any one of these HBAs.
■
To configure multiple LUN support during boot time, enter the following
command at the boot prompt:
boot: linux max_scsi_luns=128
■
If the SCSI Mid-Layer is compiled as a module, add the following line to the
/etc/modules.conf file to scan for multiple LUNs at each boot:
options scsi_mod max_scsi_luns=128
■
If the SCSI Mid-Layer is not compiled as a module, the boot loader can be
configured to scan for multiple LUNs each time the system boots.
To complete the configuration, perform the following steps:
1. Add the following line to each of the kernel images listed in the elilo.conf file:
append=”max_scsi_luns=128”
2. Reboot the system.
