0611 실습 4 ) target에 논리볼륨 디스크 추가 후, 블록스토리지(iscsi) 연결하고 initiator 2개와 연결하기

가상머신 3개 구성

1. target   192.168.122.200

2. initiator 1   192.168.122.100

3. initiator 2  192.168.122.150

 

 

[target]
스토리지 추가 후
   13  lsblk -f
   15  fdisk /dev/vdb
   16  lsblk -f
   17  pvcreate /dev/vdb1
   18  lsblk -f
   19  vgcreate vg0 /dev/vdb1
   20  lvcreate vg0 -n lv0 -L +2G 
   21  lsblk -f
   22  lvscan
   23  sudo yum install taretcli
   24  yum install targetcli*
   25  ls
   26  cd
   27  targetcli 
   28  firewall-cmd --add-port=3260/tcp --permanent 
   29  firewall-cmd --reload
   30  systemctl start target
   31  targetcli ls

targetcli iscsi 안에 iqn. server만들고 
그 안에 tpg1안  acls 안에 iqn.2020~~ client 2개 만들기
이후 룬설정
백업설정
