Set up multipath environment testing with iSCSI protocol on VMware Virtual Machine multipath (3)

ConfigurationInitiatorEnd

1. 1. Installing the Initiator software on the initiator host

# yum-y Install Iscsi-initiator-utils

1. 2. discover and connect to the Target store on the initiator host

# iscsiadm-m Discovery-t sendtargets-p192.168.136.101

# The target service is found and the information is written to the/VAR/LIB/ISCSI directory

# tree/var/lib/iscsi/# View target Information

1. 3. start the Iscsid service

#/etc/init.d/iscsid Start # start the Iscsid service first

#/ETC/INIT.D/ISCSI Start # Restart the iSCSI service This service is based on the ISCSID service information/var/lib/iscsi/to identify the device

1. 4. Check the device file name assigned to the iSCSI target device on the initiator host

# LSBLK

# tree/var/lib/iscsi/

CheckiSCSIdisk Configuration, as well as uninstall and loginScsiEquipment

# LSBLK

# tree/var/lib/iscsi/

# iscsiadm-m Node-tiqn.2017-03.centos-i1:target1–u # Uninstall, the case here is a double path

UseiSCSIdevice, and do a write operation test

1. 1. disk Partitioning (option two)

# FDISK/DEV/SDB

# PARTED/DEV/SDB

1. 2. build the file system and use

# MKFS.EXT4/DEV/SDB1

# MKDIR/ISCSI # mount the partition to the new directory/iscsi

# mount/dev/sdb1/iscsi/

# cp/home/lb/fio*/ISCSI

In the course of the experiment, if you did a SDB partition on the target side, initiator cannot see the partition. The data in the partition needs to be re-partitioned according to the parameters of the target.
