7.11. Storage Devices

You can install Fedora on a large variety of storage devices. This screen allows you to select either basic or specialized storage devices.

Figure 7.10. Storage devices

Basic Storage Devices
Select Basic Storage Devices to install Fedora on the following storage devices:
  • hard drives or solid-state drives connected directly to the local system.
Specialized Storage Devices
Select Specialized Storage Devices to install Fedora on the following storage devices:
  • Storage area networks (SANs)
  • Direct access storage devices (DASDs)
  • Firmware RAID devices
  • Multipath devices
Use the Specialized Storage Devices option to configure Internet Small Computer System Interface (iSCSI) and FCoE (Fiber Channel over Ethernet) connections.
If you select Basic Storage Devices and have only one storage device attached to your system, anaconda automatically detects the local storage attached to the system and does not require further input from you. Proceed to Section 7.13, “Initializing the Hard Disk”.

7.11.1.  The Storage Devices Selection Screen

The storage devices selection screen displays all storage devices to which anaconda has access.
Select storage devices
Screen to select available storage devices, with tabs for basic devices, firmware RAID, multipath devices, and other SAN devices.
Figure 7.11. Select storage devices

Devices are grouped under the following tabs:
Basic Devices
Basic storage devices directly connected to the local system, such as hard disk drives and solid-state drives.
Firmware RAID
Storage devices attached to a firmware RAID controller.
Multipath Devices
Storage devices accessible through more than one path, such as through multiple SCSI controllers or Fiber Channel ports on the same system.
Other SAN Devices
Any other devices available on a storage area network (SAN).
If you do need to configure iSCSI or FCoE storage, click Add Advanced Target and refer to Section 7.11.1.1, “ Advanced Storage Options ”.
The storage devices selection screen also contains a Search tab that allows you to filter storage devices either by their World Wide Identifier (WWID) or by the port, target, or logical unit number (LUN) at which they are accessed.
The Storage Devices Search Tab
The tab contains a drop-down menu to select between searching by port, target, and LUN (with corresponding text boxes for these values) and searching by WWID (with a corresponding text box for this value).
Figure 7.12. The Storage Devices Search Tab

Each tab presents a list of devices detected by anaconda, with information about the device to help you to identify it. A small drop-down menu marked with an icon is located to the right of the column headings. This menu allows you to select the types of data presented on each device. For example, the menu on the Multipath Devices tab allows you to specify any of WWID, Capacity, Vendor, Interconnect, and Paths to include among the details presented for each device. Reducing or expanding the amount of information presented might help you to identify particular devices.

Figure 7.13. Selecting Columns

Each device is presented on a separate row, with a checkbox to its left. Click the checkbox to make a device available during the installation process, or click the radio button at the left of the column headings to select or deselect all the devices listed in a particular screen. Later in the installation process, you can choose to install Fedora onto any of the devices selected here, and can choose to automatically mount any of the other devices selected here as part of the installed system.
Note that the devices that you select here are not automatically wiped by the installation process. Selecting a device on this screen does not, in itself, place data stored on the device at risk. Note also that any devices that you do not select here to form part of the installed system can be added to the system after installation by modifying the /etc/fstab file.
If you selected only one storage device, click Next and proceed to Section 7.13, “Initializing the Hard Disk”. If you selected two or more storage devices, click Next and proceed to Section 7.12, “ Assign Storage Devices ”.

7.11.1.1.  Advanced Storage Options

From this screen you can configure an iSCSI (SCSI over TCP/IP) target or FCoE (Fibre channel over ethernet) SAN (storage area network). Refer to Appendix B, ISCSI disks for an introduction to iSCSI.

7.11.1.1.1. Enable Network Interfaces
Use this dialog to configure the network interfaces through which the system will connect to networked storage devices.

Figure 7.15. Enable Network Interface

If your network does not have DHCP enabled, or if you need to override the DHCP settings, select the network interface that you plan to use from the Interfaces menu. Clear the checkbox for Use dynamic IP configuration (DHCP). You can now enter an IPv4 address and netmask for this system in the form address / netmask, along with the gateway address and nameserver address for your network.
Click OK to accept these settings and continue.
7.11.1.1.2.  Configure iSCSI Parameters
To configure an ISCSI target invoke the 'Configure ISCSI Parameters' dialog by selecting 'Add ISCSI target' and clicking on the 'Add Drive' button. Fill in the details for the ISCSI target IP and provide a unique ISCSI initiator name to identify this system. If the ISCSI target uses CHAP (Challenge Handshake Authentication Protocol) for authentication, enter the CHAP username and password. If your enviroment uses 2-way CHAP (also called "Mutual CHAP"), also enter the reverse CHAP username and password. Click the 'Add target' button to attempt connection to the ISCSI target using this information.

Figure 7.16. Configure ISCSI Parameters

Please note that you will be able to reattempt with a different ISCSI target IP should you enter it incorrectly, but in order to change the ISCSI initiator name you will need to restart the installation.
7.11.1.1.3.  Configure FCoE Parameters
To configure an FCoE SAN, select Add FCoE SAN and click Add Drive.
On the menu that appears in the next dialog box, select the network interface that is connected to your FCoE switch and click Add FCoE Disk(s).

Data Center Bridging (DCB) is a set of enhancements to the Ethernet protocols designed to increase the efficiency of Ethernet connections in storage networks and clusters. Enable or disable the installer's awareness of DCB with the checkbox in this dialog.
