1、步驟一、確認信#rpm-qa|grep device-#more 步驟一、確認信#rpm-qa|grep device-#more #/sbin/scsi_id-g -u-s #/sbin/scsi_id-g -u-s #/sbin/scsi_id-g -u-s #/sbin/scsi_id-g -u-s 步驟二、安裝HPDMMultipath HYPERLINK http:/h/ -devnodehda 2、添加多路徑 multipaths multipath devnodehda 2、添加多路徑 multipaths multipath multipath multipath #cd /m

2、nt#tar-zxvfHPDMmultipath-4.4.1.tar.gz #cd HPDMmultipath-4.4.1：#/etc/init.d/multipathd restart步驟三、配# vi /etc/multipath.confmultipath 會把所有設備都加入到（devnode *），也就是 #devnode multipath multipath /sbin/scsi_id-g-u-spath_prio_alua /sbin/scsi_id-g-u-spath_prio_alua /sbin/scsi_id-g-u-spath_prio_alua /sbin/scsi_

3、id-g-u-spath_prio_alua /sbin/scsi_id-g -u-s For /sbin/scsi_id-g-u-s For vendor /sbin/scsi_id-g-u-spath_prio_alua）步驟 vendor /sbin/scsi_id-g-u-spath_prio_alua）步驟四：查看結#multipath -db-data02(360014380125d9e2300005000000b0000)dm-1size=800Gfeatures=1_round-robin_3:0:1:2 _4:0:1:2 _round-robin_3:0:0:2 _4:0:0
