QoreStor 7.2.1 - Installation Guide

Performing the DR Series Migration

Follow the steps in the sections below to migrate your DR Series appliance. You may boot the image using either a USB key or as virtual media using iDRAC.

Creating the DR Series Migration USB

To create a DR Series Migration Image USB key, you must first contact Quest Sales to ensure proper licensing and obtain the DR Series Migration Image (.iso file). You may then transfer the image to a USB key. The USB key must be a minimum of 8 GB (Gigabytes) in size or larger.

Windows USB image tools can be used to transfer the DR Series Migration Image when they meet the following conditions:

  • Support using the .iso file format
  • Support using a direct block-to-block device copy to ensure that the USB key is bootable

NOTE: There are no system-provided Windows® utilities for creating a bootable USB drive from an IMG file. Follow the instructions for your third-party application.

To transfer the DR Series Migration Image to the USB key on a Linux or Unix system, perform the following:

  1. Copy the downloaded DR Series Migration Image iso file to a Linux or Unix system.
  2. Insert the USB key into an available USB port on the Linux or Unix system. Make note of the device name that is reported by the operating system (for example, /dev/sdc4).
  3. Do not locally mount the USB device to a file system at this time.
  4. Copy the DR Series Migration Image to the USB key using the dd command, where sdX is the device name for the USB key:
    dd if=QoreStor_Migration_7.1.0.245.iso of=/dev/sdX bs=1M

    For example:

    dd if=/root/QoreStor_Migration_7.1.0.245.iso of=/dev/sdc4 bs=4096

Migrating your DR Series Appliance using a USB key.

  1. Insert the DR Series Migration Image USB key into an available USB port on the system.
  2. Boot the DR Series system using the DR Series Migration Image USB key.
  3. During the time when the Power-On Self-Test (POST) screen displays, press F11 to load the Boot Manager.
  4. Within the Boot Manager, navigate to the system hard drive (C:), select the USB key as the boot device, and press <Enter>.
  5. The DR Series Migration Image loads and immediately begins the migration.
  6. After multiple reboots, QoreStor will initially be maintenance mode to fix refcounts, after which the server will move to operational mode.
  7. Refer to the section Initial login and changing your password for information on accessing QoreStor for the first time. Refer to Configuring QoreStor with the Configuration Menu for information on making any required configuration changes.
  8. After migration, the QoreStor server will contain two default accounts, with the default credentials as listed below. You must change the default credentials upon logging in.

    • root - the default password is generated in the format of "qorestor-<SERVICE TAG>". As an example, a machine with a service tag of 2ZQYBX1 would have a default root password of qorestor-2ZQYBX1. Root logins over SSH are disabled. Only console logins are allowed.
    • qsservice - the default password is "changeme", and must be changed after logging in.

Migrating your DR Series Appliance using iDRAC virtual media.

The iDRAC connection requires a network connection between the integrated Dell Remote Access Control (iDRAC) management port on the DR Series system and another computer running the iDRAC remote console session in a supported browser. Refer to the section iDRAC connection in the DR Series System Administrator's Guide.

  1. Using the iDRAC web interface, open the Virtual Console.
  2. Click on Virtual Media, then Launch Virtual Media.
  3. Click Add Image. Select the DR Series Migration Image iso file, then click Open.
  4. Select Mapped for connect the virtual image to the DR Series appliance.
  5. Restart the system. During the time when the Power-On Self-Test (POST) screen displays, press F11 to load the Boot Manager.
  6. Within the Boot Manager, navigate to the system hard drive (C:), select the USB key as the boot device, and press <Enter>.
  7. The DR Series Migration Image loads and immediately begins the migration.
  8. After multiple reboots, QoreStor will initially be maintenance mode to fix refcounts, after which the server will move to operational mode.
  9. Refer to the section Initial login and changing your password for information on accessing QoreStor for the first time. Refer to Configuring QoreStor with the Configuration Menu for information on making any required configuration changes.
  10. After migration, the QoreStor server will contain two default accounts, with the default credentials as listed below. You must change the default credentials upon logging in.

    • root - the default password is generated in the format of "qorestor-<SERVICE TAG>". As an example, a machine with a service tag of 2ZQYBX1 would have a default root password of qorestor-2ZQYBX1. Root logins over SSH are disabled. Only console logins are allowed.
    • qsservice - the default password is "changeme", and must be changed after logging in. .

Post-migration configurations and considerations

Some configuration data is not maintained during the migration. After the migration completes, some additional configurations may be required.

  • Domain membership is not maintained. Your new QoreStor system must be added to your domain after the migration. Refer to Configuring Active Directory Settings in the QoreStor User Guide.
  • Advanced network configurations, such as MTU configurations and NIC bonding must be reconfigured.
  • Any network changes made in the sysctl.conf filemust be reconfigured after migration.
  • In addition, QoreStor uses different data display conventions than the DR Series. Historical data for DR Series graphs not used in QoreStor is not maintained after migration.
