BMP 1a :~ # Uname-

Linux BMP 1A 2.6.16.60-0.21-smp #1 SMP Tue May 6 12:41:02 UTC 2008 x86_64 x86_64 x86_64 GNU/Linux

Therefore, install the smp version in multiple paths:

BMP 1a :~ # Rpm-ivh UltraPath-2.01.022.suse10_sp2.x86_64.smp.rpm

BMP 1a :~ # Reboot

Check whether the multi-path installation is successful:

BMP 1a :~ # Rpm-qa | grep Ul

UltraPath-2.01.022-1

BMP 1a :~ # Lsmod | grep up

UpVhba 180672 0

UpUpper 340444 1 upVhba

Scsi_mod 170936 11 mptctl, upVhba, qla2xxx, scsi_transport_fc, mptsas, mptscsih, scsi_transport_sas, libata, upUpper, sg, sd_mod

The driver has been loaded. After the multi-path software is installed successfully, two drivers exist: upVhba and upUpper, indicating that the driver has been loaded successfully.

Check whether the startup Item is changed correctly:

BMP 1a :~ # Cat/boot/grub/menu. lst

# Modified by YaST2. Last modification on Fri Nov 4 10:34:23 UTC 2011

Default 4

Timeout 8
