6.9. Creating an iSCSI LUN

Procedure

1. Create LUNs of already created storage objects:

   /iscsi/iqn.20...mple:444/tpg1> luns/ create /backstores/ramdisk/rd_backend
   Created LUN 0.
   
   /iscsi/iqn.20...mple:444/tpg1> luns/ create /backstores/block/block_backend
   Created LUN 1.
   
   /iscsi/iqn.20...mple:444/tpg1> luns/ create /backstores/fileio/file1
   Created LUN 2.

2. Verify the created LUNs:

   /iscsi/iqn.20...mple:444/tpg1> ls
   
   o- tpg.................................. [enabled, auth]
       o- acls ......................................[0 ACL]
       o- luns .....................................[3 LUNs]
       |  o- lun0.........................[ramdisk/ramdisk1]
       |  o- lun1.................[block/block1 (/dev/vdb1)]
       |  o- lun2...................[fileio/file1 (/foo.img)]
       o- portals ................................[1 Portal]
           o- 192.168.122.137:3260......................[OK]

   Default LUN name starts at 0.

   重要

   By default, LUNs are created with read/write permissions. If a new LUN is added after ACLs are created, LUN automatically maps to all available ACLs and can cause a security risk. To create a LUN with read-only permissions, see Creating a read-only iSCSI LUN.

3. Configure ACLs. For more information, see Creating an iSCSI ACL.
