Installing Proxmox Backup Server with FlashArray as Storage

This guide provides instructions on how to install Proxmox Backup Server (PBS) and configure FlashArray as backup storage using fibre channel (FC).

1. Create a virtual machine (VM) on one of the nodes and give it a generous amount of memory.
2. Access the VM using its IP address:

   https:<ip>:8007

3. Disable the enterprise repository and update:

   

   

4. Create the backup server storage:
   Note: Proxmox Backup Server datastores have to be blocked, so we will be using a volume from another storage, in this example: RedDotC.
   1. On the Proxmox nodes, update the WMID and Multipath and rescan:

      ls /sys/class/fc_host/
      echo "- - -" > /sys/class/scsi_host/hostx/scan
      ls -l /dev/disk/by-path

      

   2. Add the WMID to the Multipath configuration:

      ls -l /dev/disk/by-path
      /lib/udev/scsi_id -g -u -d /dev/sdX
      multipath -a WMID
      multipath -r
      update-initramfs -u -k all
      

   3. Create the physical volume (PV) and volume group (VG):

      pvcreate /dev/mapper/<DEVICE_NAME>
      vgcreate VG_NAME /dev/mapper/<DEVICE_NAME>

5. Create the PBS datastore:

   For more information on PBS datastores, please see the official Proxmox documentation.

   1. Locate an unused disk (in this example, it is /dev/sdb):

      

   2. Go to Administration > Storage / Disks and create a directory:

      

   3. Use the disk you previously identified, give it a name and click Create:
