This article mainly explains "Linux system how to mount iscsi storage", the content of the article is simple and clear, easy to learn and understand, the following please follow the editor's ideas slowly in depth, together to study and learn "Linux system how to mount iscsi storage" bar!

The way Linux mounts iscsi storage

There are two ways for iscsi to mount to Linux, one through ip mapping of iscsi protocol, and the other through file sharing nfs mount. Among them, through the ip mapping of iscsi protocol, it is mounted to Linux to show in the form of disk. After ip mapping, the disk needs to be partitioned and formatted.

Mounting steps:

1: check the iscsi rpm package

2: start the iscsi service and set the boot self-startup

3: find the logical volumes provided by the storage

4: map logical volumes to Linux system

5: set boot automatic mapping

6: partition the mapped disk

7: format after partition

8: Mount the partition

Note: after Linux formatting, the system file of the logical volume is the file system of Linux type. if the logical volume is to be hung on the window server, you need to reformat the logical volume, and the formatted system is the system file type of window. In short, iscsi storage mapped through ip cannot be mounted to both Linux and window, and if sharing is needed, it is best to make the storage lun for file sharing.

1. Check the iscsi rpm package

Copy the contents to the clipboard

Rpm-qa | grep iscsi

Install the RPM package

Copy the contents to the clipboard

[root@qionghai11g Packages] # rpm-Uvh iscsi-initiator-utils-6.2.0.873-2.el6.x86_64.rpm

2. Start the iscsi service and set the boot self-startup

Copy the contents to the clipboard

[root@qionghai11g Packages] # service iscsi start

[root@qionghai11g Packages] # chkconfig-- list | grep iscsi

3. Find the logical volumes provided by the storage

Copy the contents to the clipboard

[root@qionghai11g] # iscsiadm-m discovery-t sendtargets-p 192.16.10.188 purl 3260

Starting iscsid: [OK]

192.16.10.188 purl 3260 iqn.2004-01.com.storbridge:block02-wt

192.16.10.188 purl 3260 iqn.2004-01.com.storbridge:block01-wt

4. Map logical volumes to Linux system

Copy the contents to the clipboard

[root@qionghai11g] # iscsiadm-m node-T iqn.2004-01.com.storbridge:block01-wt-p 192.16.10.188 purl 3260-l

Logging in to [iface: default, target: iqn.2004-01.com.storbridge:block01-wt, portal: 192.16.10.188 Magi 3260] (multiple)

Login to [iface: default, target: iqn.2004-01.com.storbridge:block01-wt, portal: 192.16.10.188 Magi 3260] successful.

[root@qionghai11g] # iscsiadm-m node-T iqn.2004-01.com.storbridge:block02-wt-p 192.16.10.188 purl 3260-l

Logging in to [iface: default, target: iqn.2004-01.com.storbridge:block02-wt, portal: 192.16.10.188 Magi 3260] (multiple)

Login to [iface: default, target: iqn.2004-01.com.storbridge:block02-wt, portal: 192.16.10.188 Magi 3260] successful.

5. Set automatic mapping for boot.

Copy the contents to the clipboard

[root@qionghai11g] # iscsiadm-m node-T iqn.2004-01.com.storbridge:block02-wt-p 192.16.10.188 iqn.2004 3260-- op update-n node.startup-v automatic

[root@qionghai11g] # iscsiadm-m node-T iqn.2004-01.com.storbridge:block01-wt-p 192.16.10.188 iqn.2004 3260-- op update-n node.startup-v automatic

These two are automatically mapped on the boot.

6. Partition the mapped disk

Since the storage capacity is 12T and greater than 2T, different partitions fdisk cannot be used, only GPT partitions can be used.

Parted / dev/sdb partitions / dev/sdb

Print print information, from which you can see the disk size and partition format

Mklabel gpt

Mkpart primary 0% 100%

Print can see that the disk partition format has changed to GPT.

7. Format after partition

Copy the contents to the clipboard

[root@oracle11g ~] # mkfs.ext3 / dev/sdb

Mke2fs 1.39 (29-May-2006)

/ dev/sdb is entire device, not just one partition!

This filesystem will be automatically checked every 23 mounts or

180 days, whichever comes first. Use tune2fs-c or-i to override.

8. Mount the partition

[root@qionghai11g ~] # cd / var/www/html/

[root@qionghai11g html] # mkdir kk1 kk2

[root@qionghai11g mnt] # mount / dev/sdb1 / var/www/html/kk1/
