HP StorageWorks Storage Mirroring for Linux Getting Started (T2558-96077, February 2008)

Server Requirements
Verify that each machine that will be used as a Storage Mirroring source or target meets the following system requirements.
! Operating System—Each server must be running a 32-bit or 64-bit version of Red Hat
®
Enterprise Linux
®
4.2 through
4.5.
! System memory—At a minimum, you should have 512 MB of memory on each server. Ideally, you should have 1 GB.
! Disk Usage—The amount of disk space required for the Storage Mirroring program files is approximately 45 MB. About
5 MB will be located on your
/(root) partition, and the remainder will be on your /usr partition. You will need to
verify that you have additional disk space for Storage Mirroring queuing, logging, and so on. Additionally, on a target
server, you need sufficient disk space to store the replicated data from all connected sources, allowing additional space
for growth.
! Protocols—TCP/IP
! File System—Storage Mirroring supports the ext2 and ext3 file systems. Storage Mirroring is compatible with NFS and
Samba as long as they are mounted on top of Storage Mirroring. Storage Mirroring should be mounted just above the
storage file system.
Installing Storage Mirroring
Use these instructions if you are installing Storage Mirroring for the first time or if you have completely uninstalled any
previous version of Storage Mirroring.
1. Go to a shell prompt by launching a terminal application from your graphical user interface (GUI) or logging in via the
Linux virtual console.
2. If you are not already, become the superuser ("root") by typing su -.
3. Determine the installation package that is appropriate for your operating system.
The versionnumbers in the installation file name will vary and will correspond to the version of Storage Mirroring you
are installing. For example, if you are installing version
4.3.10.0.1815, the installation files would be
StorageMirroring-4.3.10.0-1815.i386.rpm or StorageMirroring-4.3.10.0-1815.x86_64.rpm. If you
are uncertain about the architecture of your machine, you can use the uname -m command to determine it.
4. If you are installing from a CD, mount the file ISO 9660 or UDF file system and run the installation file appropriate for
your operating system. If you are installing from a web download, verify you have the installation file appropriate for your
operating system and then run the installation program.
To run the installation use
rpm -i with the installation file name. For example, if you were installing on a 32-bit
operating system, you would use the command
rpm -i StorageMirroring-4.3.10.0-1815.i386.rpm.
A successful installation returns you to the shell prompt. If you receive an error message during the installation, you will need
to reinstall the software. If you are unable to resolve the error, contact technical support.
