StorNext 3.1.3 Installation Guide 3

Chapter 1 Installing StorNext File System and Storage Manager

Storage Manager System Requirements

Partitioning Local Hard Disks 1

StorNext can be installed on any local file system (including the root file system) on the MDC. However, for optimal performance, as well as to aid disaster recovery, follow these recommendations:

• Avoid installing StorNext on the root file system.

• Partition local hard disks so that the MDC has four available local file systems (other than the root file system) located on four separate hard drives.

Note: You can run the pre-installation script to help determine the

estimated size of and optimal location for StorNext support directories. For more information, see

Pre-Installation Script

on page 8.

LAN Requirements 1

The following LAN requirements must be met before installing StorNext on the MDC:

• In cases where gigabit networking hardware is used and maximum StorNext performance is required, a separate, dedicated switched Ethernet LAN is recommended for the StorNext metadata network. If maximum StorNext performance is not required, shared gigabit networking is acceptable.

• A separate, dedicated switched Ethernet LAN is mandatory for the metadata network if 100 Mbit/s or slower networking hardware is used.

• The MDC and all clients must have static IP addresses.

Verify network connectivity with pings, and also verify entries in the

/etc/hosts file.

• If using Gigabit Ethernet, disable jumbo frames and TOE (TCP offload engine).

Note: StorNext does not support file system metadata on the same

network as iSCSI, NFS, CIFS, or VLAN data when 100 Mbit/s or slower networking hardware is used.

StorNext 3.1.3 Installation Guide 4

Getting Ready to Install

Before installing StorNext SNFS and SNSM, complete the following tasks to ensure successful installation:

• Correctly configure all storage devices (see Configuring Storage

Devices).

• If using LUNs larger than 1 TB, decide on a label type and install any necessary operating system patches (see

than 1 TB).

• (Linux only) Install the kernel source code (see Installing the Linux

Kernel Source Code on page 7).

Chapter 1 Installing StorNext File System and Storage Manager

Getting Ready to Install

Planning for LUNs Larger

Configuring Storage Devices 1

Planning for LUNs Larger than 1 TB 1

Before installing StorNext SNFS and SNSM, make sure that all LUNs are visible to the MDC. (A LUN, or logical unit number, is a logical device that corresponds to one or more disks, drives, or storage devices.)

If there are any connection issues, resolve them before installing StorNext. For assistance in configuring storage devices, refer to the documentation that came with the storage device, or contact the manufacturer.

Note: LUNs that you plan to use in the same stripe group must be

the same size. Consider this when configuring storage devices. (For more information about stripe groups, see the StorNext

3.1.3 User’s Guide.)

Caution: StorNext does not support the connection of multiple

devices through fibre channel hubs. Multiple devices must be connected using fibre channel switches.

StorNext supports LUNs greater than 1 TB in size if they are allowed by the operating system. To enable support for 1 TB or larger LUNs, all StorNext LUNs must be correctly labeled according to the requirements

StorNext 3.1.3 Installation Guide 5

of the operating system running on the MDC as well as the operating system running on all connected clients. Disk LUNs can have one of three labels: VTOC, EFI, or sVTOC (short VTOC).

Required disk LUN label settings based on operating system and LUN size are presented in

Table 3. Before installing StorNext, decide what

label type will be used, and then install any required operating system patches or updates (for both MDC and client) as indicated in the notes for

Table 3.

Note: After labeling a disk LUN, you must reboot systems running

Solaris before they can access the disk LUN.

Note: For best results, Quantum recommends using persistent

binding for disk LUNs. For more information, contact the vendor of your HBA (host bus adapter).

For management servers running Red Hat Enterprise Linux version 4 or 5, before installing SNFS and SNSM you must first install the kernel header files (shipped as the kernel-devel or kernel-devel-smp RPM, depending on your Linux distribution).

For servers running SUSE Linux Enterprise Server, you must install the first kernel source code (shipped as the kernel-source RPM). StorNext will not operate correctly if these packages are not installed. You can install the kernel header files or kernel source RPMs by using the installation disks for your operating system.

Verifying Hostname Length 1

The maximum hostname length for a StorNext server is limited to 25 characters. Before you begin the installation, verify that the destination hostname is not longer than 25 characters. (The hostname is read during the installation process, and if the hostname is longer than 25 characters the installation process could fail.)

StorNext 3.1.3 Installation Guide 7

Pre-Installation Script

The StorNext pre-installation script (snPreInstall) is included on the StorNext installation CD. When you run for information about your system. The pre-installation script uses this information to estimate the amount of local disk space required for SNFS and SNSM support directories. In addition, the script recommends the optimal locations for support directories.

StorNext uses five directories to store application support information. These directories are stored locally on the metadata controller, except for the

Backup directory, which is stored on the managed file system.

The StorNext support directories are described in Table 4.

Contains configuration files and support data required for disaster recovery.

Before running the pre-installation script, be prepared to answer the following questions:

• Is this an upgrade installation?

• What local file systems can be used to store support information?

• Which version of StorNext will be installed?

StorNext 3.1.3 Installation Guide 8

Chapter 1 Installing StorNext File System and Storage Manager

Pre-Installation Script

• What is the maximum number of directories expected (in millions)?

• What is the maximum number of files expected (in millions)?

• How many copies will be stored for each file?

• How many versions will be retained for each file?

Note: Keep in mind that storage needs typically grow rapidly.

Consider increasing the maximum number of expected directories and files by a factor of 2.5x to ensure room for future growth.

Note: The pre-installation script ignores unmounted file systems.

Before running

snPreInstall, be sure to mount all local file

systems that will hold StorNext support information.

Running snPreInstall 1

To run the pre-installation script, use the StorNext installation CD.

1 Log on to the MDC as root. 2 Mount the StorNext installation CD and change to the CD root

directory.

3 List the installation directories on the CD. At the command prompt,

type:

ls -l

4 Identify the correct installation directory for your operating system

and hardware platform, and then change to that directory.

For example, for Red Hat Linux 4 running on an x86 64-bit platform, change to the

RedHat40AS_26x86_64 directory.

5 Run the script. At the command prompt, type:

./snPreInstall

The pre-installation script runs (figure 1).

Pre-Installation Script

6 Follow the onscreen instructions, and answer each question when

prompted.

The script outputs results based on the information you entered.

Interpreting snPreInstall Output 1

After you enter all requested information, the pre-installation script outputs the following results:

• Estimated disk space required for each support directory.

• Recommended file system location for each support directory.

Tech Tip: For optimal performance, each support directory

(other than the

Backup directory) should be located on

its own local file system, and each local file system should reside on a separate physical hard disk in the MDC.

There are three types of directory recommendations, as indicated by the text preceding the recommendation. The three types of recommendations are described in

StorNext 3.1.3 Installation Guide 10

Table 5.

Chapter 1 Installing StorNext File System and Storage Manager

Pre-Installation Script

Table 5 Pre-Installation Script Recommendation Types

Type Description

RECOMMEND The suggested directory locations will result in

optimal system performance.

NOTE The suggested directory locations are valid but

system performance will not be optimal.

SPACE Additional hard disk space is required to store

the required support directories.

The pre-installation script bases directory location recommendations on the following criteria:

• To aid disaster recovery, the Database and Journal directories should

be located on different file systems.

• For optimal performance, the Metadata directory should not be

located on the same file system as (in order of priority) the

Database, or Mapping directory.

Journal,

Note: Do not change the location of support directories manually.

Instead, use the installation script to specify the location for support directories. For more information, see

Launching the StorNext Installation Script 1

The StorNext installation script lets you choose installation configuration options and install StorNext. To launch the script, use the correct StorNext installation CD for your operating system.

1 Log on to the MDC as root. 2 Mount the StorNext installation CD and change to the CD root

directory.

Note: When you mount a CD in a Red hat 4 or 5 system, CDs are

mounted by default with a noexec (non-executable) option which prevents you from proceeding with the installation.

For Red Hat users only, before proceeding you must

remount the CD by typing mount -o remount, exec ...

3 List the installation directories on the CD. At the command prompt,

type:

ls -l

4 Identify the correct installation directory for your operating system

and hardware platform, and then change to that directory.

For example, for Red Hat Linux 4 running on an x86 64-bit platform, change to the

RedHat40AS_26x86_64 directory.

5 Run the script. At the command prompt, type:

./install.stornext

The installation script runs (figure 2).
