How to enable Red Hat Enterprise Linux4 to support multi-LUN-Linux Enterprise Application-Linux server application information is as follows. Affected Versions: Red Hat Enterprise Linux4

Unlike earlier versions of Red Hat Enterprise Linux, You need to modify the/etc/modprobe. conf file instead of the/etc/modules. conf file when setting multi-LUN support in Red Hat Enterprise Linux4.

The option that supports multiple Luns is options scsi_mod max_luns = xxx. Note that this option is different from that used in earlier versions of Enterprise Linux. RHEL3/2 uses options scsi_mod max_scsi_luns = xxx.

The configuration steps for Red Hat Enterprise Linux4 are as follows:

1. Add the following content to/etc/modprobe. conf

Options scsi_mod max_luns = xxx
(Xxx is the number of Luns that scsi_mod needs to support, for example, 128)

2. To make the modification valid, create a memory disk for startup

Mkinitrd-f/boot/newimage-2.6.xx 2.6.xx
(Xx must be replaced by the kernel version)

3. After the operating system is restarted, all LUNs should be identified.
