One Identity Safeguard for Privileged Sessions 5.9.0 - Installation Guide

High Availability and redundancy in Microsoft Azure

In a Microsoft Azure deployment, the high-availability and redundancy of the SPS appliance is provided by the Microsoft Azure infrastructure, according to the Azure Storage SLA.

Redundancy

The data in your Microsoft Azure storage account is always replicated to ensure durability and high availability, meeting the Azure Storage SLA. The exact type of replication depends on your storage account settings, but every disk is stored in 3 copies.

For details, see Locally redundant storage in the Azure Storage replication document, and Service Healing - Auto-recovery of Virtual Machines.

High Availability

If a hardware failure occurs, Azure moves the Virtual Machine to another location and restarts it in 5-15 minutes. In case you require higher SLA, you are recommended to deploy two standalone SPS nodes into an availability set. Note that to deploy two active SPS nodes as an availability set, you must purchase two standalone SPS licenses.

For details, see Locally redundant storage in the Azure Storage replication document, and Service Healing - Auto-recovery of Virtual Machines.

Virtual appliance maintenance

Modifying the disk size of a SPS virtual appliance

Purpose:

SPS can only use fixed disk space assigned to the virtual host. If you must increase the size of the virtual disk, complete the following steps. Online disk resize can grow the filesystem up to 1024x size of the original size.

Prerequisites:

You can resize the disk that way only if you originally installed SPS version 5 LTS or later. This method will not work if you upgraded to 5 LTS from an earlier version.

Steps:
  1. Warning! Hazard of data loss!

    Create a full system backup (configuration and data backup). For detailed instructions, see "Data and configuration backups" in the Administration Guide.

  2. Power down the virtual machine.

  3. Increase the storage size.

  4. Power on the SPS virtual machine.

  5. Login to SPS as root locally (or remotely using SSH) to access the Console menu.

  6. Select Shells > Boot Shell.

  7. Issue the following command: parted /dev/Xda resizepart

    Letter X might vary on different systems. Usually it is 's' or 'v'. Check your system before issuing this command.

  8. Answer the on-screen questions with the following answers:

    • Fix/Ignore? > fix

    • Partition number? > 4

    • Warning: Partition /dev/sda4 is being used. Are you sure you want to continue? Yes/No? > yes

    • End? > -0

    • Fix/Ignore? > fix

    For example:

    (boot/master/ip99)root@scb1:~# parted /dev/sda resizepart
    Warning: Not all of the space available to /dev/sda appears to be used, you can fix the GPT to use all of the space (an extra 4194304 blocks) or continue with the current setting?
    Fix/Ignore? fix
    Partition number? 4
    Warning: Partition /dev/sda4 is being used. Are you sure you want to continue?
    Yes/No? yes
    End?  [22.5GB]? -0
    Information: You may need to update /etc/fstab.
  9. Issue the following command: resize2fs /dev/Xda4

    Letter X might vary on different systems. Usually it is 's' or 'v'. Check your system before issuing this command.
