Verifying the Fibre Channel connections

You must identify the disk volume on the external Fibre Channel device. If required, you must also create a partition on the volume.

Before you begin

Verify your Emulex adapter installation.

Procedure

Attach both Fibre Channel cables to the Emulex LPe12002 or LPe16002B Host Bus adapter on your QRadar Console appliance.
Using SSH, log in to your QRadar Console as the root user.
Identify the Fibre Channel volume by typing the following command:
```
ls -l /dev/disk/by-path/*-fc-*
```
If multiple Fibre Channel devices are attached and you cannot identify the correct Fibre Channel volume, contact your system administrator.
Optional: If there is no partition on the Fibre Channel volume, then create a partition on the Fibre Channel device volume.

Note: QRadar does not support the creation of a partition on a Logical Volume Manager (LVM) drive. The file system fails to mount during a system boot, when a partition is created on an LVM drive.
1. Optional: To create a partition, use the GNU parted command:
```
parted /dev/<volume>
```
2. Configure the partition label to use GPT by typing the following command:
```
mklabel gpt
```
3. If the following message is displayed, type Yes.
```
Warning: The existing disk label on /dev/<volume> will be
destroyed and all data on this disk will be lost. Do you want to
continue?
```
4. To create the partition, type the following command:
```
mkpart primary 0% 100%
```
5. Set the default units to TB by typing the following command:
```
unit TB
```
6. Verify that the partition is created by typing the following command:
```
print
```
7. Exit from GNU parted by typing the following command:
```
quit
```
8. Update the kernel with the new partition data by typing the following command:
```
partprobe /dev/<volume>
```
  You might be prompted to restart the appliance.
9. To verify that the partition is created, type the following command:
```
cat /proc/partitions
```
Reformat the partition and make a file system.
- To create an XFS file system, type the following command:
```
mkfs.xfs -f /dev/<partition>
```
- To create an ext4 file system, type the following command:
```
mkfs.ext4 -f /dev/<partition>
```
- To create an XFS file system for multipath Fibre Channel, type the following command:
```
mkfs.xfs -f -L multiPath /dev/<partition>
```
- To create an ext4 file system for multipath Fibre Channel, type the following command:
```
mkfs.ext4 -f -L multiPath /dev/<partition>
```

If you are moving the /store file system to a Fibre Channel solution, go to Moving the /store file system to a Fibre Channel solution.

If you are moving the /store/ariel file system to a Fibre Channel solution, go to Moving the /store/ariel file system to a Fibre Channel solution.

If you are moving the /store file system to a multipath Fibre Channel solution, go to Moving the /store file system to a multipath Fibre Channel solution.

If you are moving the /store file system to a multipath Fibre Channel solution in an HA deployment, go to Moving the /store file system to a multipath Fibre Channel solution in an HA deployment.
