Introduction


Mistika 8.6 will be supported in the following operating system:


* SUSE 11 SP3  (both Mistika 8.5 and Mistika 8.6 can coexist on it). The Suse11 SP3 OS is near end of life, but it can run both 8.5 and 8.6 to provide a transition period


* CentOS 7.2 (only Mistika 8.6 and later).  This is the default for new installations and it is future proof, but it can not run previous 8.5 versions.  


Systems using Suse11 SP1 or SP2 need to be upgraded to one of those options. But this document only cover the case of Suse11 SP3  (The other case to upgrade to CentOS 7.2 is described in the Mistika 8.6 Release Notes document )


To know which exact operating system you have execute this command in a console


cat /etc/issue


Before you start (For clients using Stornext SAN)


Clients using old SUSE 11 SP1 systems will have old versions of Stornext  filsystem. They will need to upgrade the Stornext license  BEFORE doing the upgrade. 


If you have a dedicated  metadata controller server (MDC) running Suse11 Sp1, then this is the first system that will need to be upgraded. Please contact SGO support if that is the case.


Note: Clients in the need of a Stronext license upgrade should consider a direct upgrade to SN5 and CentOS7.2, as depending on the configuration the cost can be pretty similar and the benefits are higher


Recommended upgrade method


The general idea is to prepare the upgrade having the chance to return at any moment to the previous configuration in case of emergency.

And for this reason we will use a different system disk to install SUSE 11 SP3, so you can boot still with old one if neccesary.


Preparation.

  • Backup any user data existing in the system disk

  • Buy or get a new hard disk (recommended: SATA disk, 3,5”, at least 500 GB. 7200rpm.)

  • Contact SGO support to plan the collection of configuration data and to get the latest iso download for the new OS.


NOTE: Suse 11 SP3  will need to be installed with the Mistika installation iso.  Custom installations not using the official Mistika iso will not be supported (they would require a huge amount of additional packages and customisation that is not documented anywhere ).


  • Create a USB pen drive with the new iso


Procedure.

  • Get the new system disk.

  • Confirm you have the  Backup of Media, Projects and configuration.

  • Download  the new ISO from our FTP site (around 6GB).

  • Burn a DVD (double side) or a Pen Drive. See “ISO Installation” below

  • Power Off Mistika.

  • Disconnect all external storage (all Fiber Channel cables and external disks. This point is specially important).

  • Remove the current System Disk and labelled as SP1 or similar.

  • Insert the new system disk.

  • Insert the Pen Drive or Installation DVD and power on the Workstation (chose to boot from DVS or USB as needed)

  • Follow the procedure below. “SUSE 11 SP3 Installation Procedure for Customers”

  • Once installed and internet access is configured, contact Support again to arrange for a remote installation appointment to make the final configuration. (meanwhile, you can power off the system, swap boot disks and reconnect all the storage, to continue using it with the old one until the appointment.

        When the support appointment arrives:

  • Power off and swap disks to boot with the new system disk. Also connect the OLD SYSTEM disk in other slot of the workstation or in a external dock, to provide access to old configuration settings to the support engineer

  • Power On the system.

  • Open a remote session and give access to the SGO engineer to finish the configuration.


ISO Installation


IMPORTANT NOTE: 

Always disconnect all the storage devices before installing the operating system. otherwise they will at high risk during the OS installation (mainly because the installer may want to use them as destination targets by default ).


If you need to install or reinstall the operating system, please contact support to get the latest iso.

Once you download the iso, you can burn it in a DVD (it must be a double side DVD because of the size ) or in a pen drive (recommended).


To install it in a pen drive, download the iso to the Mistika system and execute this from a Linux system:


su

dd if=Path_To_ISO_file of=/dev/sdX


Where X is the device letter assigned to the pendrive (just one letter with no numbers at the end). If you are not sure execute this:


su

tail -f /var/log/messages


Now plug the pen drive, the assigned device will appear somewhere in the console output.  You have to use the device id without any partition number ( for example  /dev/sdc, not /dev/sdc1 )

Please only continue if you are sure about the pen drive device, otherwise please contact support.  This step is critical because choosing the wrong device you can destroy all data in your system disks or in the disk array.

For example, if you have downloaded a SUSE iso named SGO_INSTALLER_SP3_MTK_8511_NV_352_DVS435_AJA_Z840.iso and the pendrive has been assigned /dev/sdc, you have to execute something like this :


su

dd  if=SGO_INSTALLER_SP3_MTK_8511_NV_352_DVS435_AJA_Z840.iso   of=/dev/sdc


It will take several minutes. Then, boot with the pendrive and follow instructions.



SGO Mistika. SUSE 11 SP3. Installation Procedure.


1.- BIOS parameter setup. Z820 / Z800.


Connect to the workstation keyboard, mouse and monitor. Power on system.

When the blue screen appears press F10. You will access BIOS Setup menu.

Confirm the right boot order for the operating system installation. 


F10 > Storage > Boot Order > Legacy Boot Sources > 


ATAPI CD/DVD Drive

USB Floppy/CD

Hard Drive

Ethernet Network Controller


If this is not right you can force the boot from the DVD or USB Pen Drive using this way


F9 > Entering Boot menu >  Legacy Boot Sources > Choose DVD or USB (depending your installing device) 


In both cases the installation process should start.


2.- Suse Linux Enterprise Desktop 11 SP3 Installation.


Make sure the only disk in the system is the new empty disk for the new OS


Introduce the installation DVD in the DVD Player before power off workstation.


VERY IMPORTANT.


Disconnect or unplugged all Arrays and external drives connected to the system.
Power on workstation.

System should boot from the DVD  or pen drive to start the installation process.

This installation iso includes the following items.


  • Suse Linux Enterprise Desktop 11. SP3.

  • Graphic Board drivers.

  • Video Board drivers.

  • FC drivers

  • Stornext drivers.

  • Other third party software 

  • Mistika.


Installation procedure is as follow.


  • The system begins booting from the DVD or pen drive.

  • In less than 10 seconds it must start the graphical installation interface.

During process there are two reboots. Wait until process finish completely. 

This process can spend between 60 and 90 minutes, depending of the workstation.


Once finish “Installation completed” appear on screen. 

Press “Finish” and system make a reboot.


After reboot appear a message concerning Audio board.


“KDE detected that one or more internal sound devices were removed. 

Do you want KDE to permanently forget about these devices?”  

Do not ask again = Enable


Power off system and reconnect all arrays and external drives.


Power on system and set the network.


4.- Network configuration.


Plug the network connector to local network.

By default the configuration is on DHCP and the system should has IP address and have Internet access, but in case don’t, please follow reading this document. 

To set up network we need to know this data:


  1. IP for eth0.

  2. Mask (Normally 255.255.255.0 or /24)

  3. IP for Gateway

  4. IP for  DNS Server.


Start Yast. 

  • Start  >  Yast (Administrator Settings)  

  • Type root password to start Yast  >  Password = mistika  >  OK.

  • Network Device  >  Network Settings

  • Overview 

    • Show two interfaces for Z800 and Z820.

    • Select interface associated to eth0  >  Edit.

      • Network Card Setup

  1. Address.

    1. Statically assigned IP Addres = Enable

    2. IP Address = Set the IP Address.

    3. Subnet Mask = /24 = 255.255.255.0

    4. Hostname = mistika

  2. Next

  • Routing  =  IP address for Gateway.

  • Next

  • Ok.


Check that you have internet connection and contact SGO Support to stablish an appointment to connect remotely.


Alternatively,  for system administratris who decide to configure it by themsevelves they can mount the old boot disk as a second disk for a reference, and get all the licenses and important configuration files and other settings from there.
