Setting Up a Unix Host to Use VNXe Generic iSCSI Storage c. Set the initiator CHAP password (secret) to the same secret that you entered for the host initiator on the VNXe system. For mutual CHAP: a. Enable outgoing authentication (mutual CHAP). b. Set the mutual CHAP username to the initiator's IQN, which you can find with the iscsiadm -m node command. c. Set the initiator password (secret) for the target to the same secret that you entered for the VNXe iSCSI Server. 8. Find the driver parameter models you want to use, and configure them as shown in the examples in the configuration file. 9. Restart the iSCSI service. Task 2: Set up the Linux host to use the VNXe iSCSI virtual disk Perform the following tasks as described in the Linux operating system documentation: 1. Find the LUN number of the virtual disk: a. In Unisphere, select Storage > Generic iSCSI Storage. b. Select the generic storage with the virtual disk, click Details, and click the Virtual Disks tab. 2. On the host, partition the virtual disk. If the host does not see the virtual disk, you can have problems with the iSCSI session between the host and an iSCSI target (VNXe iSCSI Server). To troubleshoot this problem, see "iSCSI session troubleshooting" on page 64. 3. Create a file system on the partition. 4. Create a mount directory for the file system. 5. Mount the file system. The Linux host can now write data to and read data from the file system on the virtual disk. Linux host - Setting up for Generic iSCSI storage 61

Linux host — Setting up for Generic iSCSI storage
61
Setting Up a Unix Host to Use VNXe Generic iSCSI Storage
c.
Set the initiator CHAP password (secret) to the
same
secret that you entered for the
host initiator on the VNXe system.
For mutual CHAP:
a.
Enable
outgoing
authentication (mutual CHAP).
b.
Set the mutual CHAP username to the initiator’s IQN, which you can find with the
iscsiadm -m node
command.
c.
Set the initiator password (secret) for the target to the
same
secret that you
entered for the VNXe iSCSI Server.
8.
Find the driver parameter models you want to use, and configure them as shown in the
examples in the configuration file.
9.
Restart the iSCSI service.
Task 2: Set up the Linux host to use the VNXe iSCSI virtual disk
Perform the following tasks as described in the Linux operating system documentation:
1.
Find the LUN number of the virtual disk:
a.
In Unisphere, select
Storage
>
Generic iSCSI Storage
.
b.
Select the generic storage with the virtual disk, click
Details
, and click the
Virtual
Disks
tab.
2.
On the host, partition the virtual disk.
If the host does not see the virtual disk, you can have problems with the iSCSI session
between the host and an iSCSI target (VNXe iSCSI Server). To troubleshoot this
problem, see
“iSCSI session troubleshooting” on page 64
.
3.
Create a file system on the partition.
4.
Create a mount directory for the file system.
5.
Mount the file system.
The Linux host can now write data to and read data from the file system on the virtual disk.
