Boot server requirements

More information is available about the SRT requirements that are related to boot servers.

Table: Boot server requirements

Type of server

Requirements

General boot server

You must have a boot server for each type of client that you want to protect. For example, a Solaris client requires a Solaris boot server, a Windows client requires a Windows boot server, and so on.

For UNIX, Linux, and legacy Windows restores, a boot server at a particular operating system version can only host SRTs of the same operating system version or lower. For example, a Solaris 9 boot server can host Solaris 8 and Solaris 9 SRTs, but not Solaris 10 SRTs.

For UNIX, Linux, and legacy Windows restores, a client at a particular operating system version requires an SRT of the same operating system version.

Refer appendix Network services configurations on BMR Boot Server to know details about network-based recovery pre-requisite setup for different platforms.

AIX boot server

AIX boot servers do not have any special requirements. An AIX boot server can reside on the same subnet as the subnet of the client, or on a different subnet. However, AIX boot servers at a specific operating system version can only host SRTs of the same or earlier operating system version. For example, a 5.3.0.10 boot server can only host 5.1.x.x, 5.2.x.x, 5.3.0.0, and 5.3.0.10 SRTs, but not 5.3.0.20 SRTs. Likewise, a 5.2.x.x boot server cannot host 5.3.x.x SRTs.

Also, to recover 5.3.0.10 client, you need to create 5.3.0.10 SRT. You cannot use 5.3.0.11 or 6.1.0.1 SRT to recover this client.

HP-UX boot server

Each network segment with HP-UX clients must have an HP-UX boot server that can support the clients.

On an HP-UX boot server, the Ignite version of an SRT must match the Ignite version that is installed on the boot server.

Linux boot server

Each network segment that has Linux clients must have a Linux boot server.

Though in case of VLAN (Virtual Local Area Network) setup case, you can configure your switch settings to route network boot requests packets to the server located at other VLAN than where client exists. This way a single Linux boot server can recover Linux clients belonging to different VLANs.

Solaris boot server

Each network segment with Solaris clients must have a Solaris BMR boot server that can support the clients.

However, you can use the following to minimize the effect of this requirement:

  • When necessary, you can install BMR boot server software on a Solaris computer in the network segment. Then create an SRT after the client has failed and needs to be restored.

  • The Solaris BMR boot server can be defined on a Solaris computer that has a physical IP presence on multiple networks.

    That is, you can use a single Solaris BMR boot server with multiple network interfaces for Solaris BMR clients on each network segment.

  • Configure a relay boot server to allow Solaris computers on remote subnets to boot from a BMR boot server using a network gateway.

  • You can contact support representative to get more information.

  • The BMR boot server for Solaris10_x64 requires the following software installed:

    • TFTP Server

    • DHCP server

    • NFS Server

    • SRTs for carrying out a bare metal restore of a Solaris10_x64 client can only be created and hosted on a Solaris10_x64 Boot server. The OS and Kernel level should be greater than or the same of the client to be restored.

    If you want to use bmrsrtadm Media Creation to generate BMR-ISO SRTs, you must install the SUNWmkcd package on the boot server.

Windows boot server

Windows boot server requirements are as follows:

  • The network boot services on the boot server require a DHCP server somewhere on the network.

  • The boot server must not run a PXE service or a TFTP service.
