How to enable SAN Connectivity and RAID Controller using HBA Card?

Info
HBA Card is used for enabling communication between servers and storage devices 









SAN (Storage Area Network

A Storage Area Network (SAN) is a specialized, high-speed network that provides block-level network access to storage

RAID Controller

RAID (redundant array of independent disks) is a way of storing the same data in different places on multiple hard disks or solid-state drives (SSDs) to protect data in the case of a drive failure.

How to enable SAN Connectivity

  1. Physically Install the HBA Card:
    1. Insert the HBA card into an appropriate PCIe slot on the server motherboard.
    2. Connect the cables: Attach the Fibre Channel (FC) or iSCSI cables from the HBA card to the SAN switch or storage device.
  2. Enter the BIOS or UEFI to verify the HBA card is detected.
  3. Verify HBA Firmware and Driver
    1. Linux: Use lspci or dmesg | grep -i hba to check if the system recognizes the HBA.
    2. Windows: Check Device Manager under "Storage Controllers."
  4. Configure HBA Settings
    1. Access the HBA BIOS
    2. Press the key combination (e.g., Ctrl+Q, Ctrl+C, Ctrl+E) during server boot to enter the HBA card's BIOS settings.
  5. Configure the HBA card
    1. Set up the FC/iSCSI initiator.
    2. Set the WWPN (World Wide Port Name) or IP address (for iSCSI).
  6. Connect to the SAN
    1. Configure zoning on the SAN switch for Fibre Channel connections.
    2. Use the switch management interface to add the WWPN of the HBA to the correct zone.
    3. For iSCSI, configure the target and initiator settings, including the IQN (iSCSI Qualified Name) and IP addresses.
  7. Scan for Storage Devices
    1. Linux: Use commands like rescan-scsi-bus.sh, echo "- - -" > /sys/class/scsi_host/hostX/scan, or tools like multipath -ll for multipath storage.
    2. Windows: Use Disk Management or the iSCSI Initiator utility to discover and connect to the SAN storage.

How to enable RAID Controller

  1. Enable RAID Mode
  2. Once in the HBA/RAID BIOS utility:
  3. Look for the Operating Mode or HBA Mode setting.
  4. Switch from HBA (Passthrough) mode to RAID Mode.
  5. Save the changes and reboot the server.
