Chapter 1

Installing StorNext File System

and Storage Manager

This chapter describes how to install StorNext File System (SNFS) and StorNext Storage Manager (SNSM) on a metadata controller (MDC). Install both SNFS and SNSM for storage systems that require policybased data movement (for example, systems that include tape drives or libraries).

To ensure successful operation, do the following tasks before installing StorNext:

• Make sure the MDC meets all operating system and hardware requirements (see

• Make sure all storage devices are correctly configured and are visible to the MDC (see

Storage Manager System Requirements).

Getting Ready to Install on page 5)

• (Optional) Run the pre-installation script to check for available disk space and view recommended locations for support directories (see

Pre-Installation Script on page 8).

When you are ready to install StorNext File System and Storage Manager on the MDC, run the installation script (see on page 11).

Note: To install only StorNext File System (without Storage Manager),

Chapter 1: Installing StorNext File System and Storage Manager Storage Manager System Requirements

Partitioning Local Hard Disks

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 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. Alternatively, telnet or ssh between machines to verify

connectivity.

• 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.

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

Planning for LUNs Larger than 1 TB

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

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 of the operating system running on the MDC as well as the operating

a. For Windows XP 32-bit systems only, support for LUNs larger than 2 TB is

limited to the first 2 TB. All other supported Windows platforms

(including Windows XP 64-bit) support LUNs greater than 2 TB. b. Support for EFI labels requires the Multiterabyte Disk Support patch. c. Support for 2 TB or larger LUNs requires Solaris 10 Update 2 (06/06). d. Supports only the first 2 TB of LUNs larger than 2 TB. e. Supports only LUNs of 2.2 TB or less.

Label for LUNs < 1 TB

Label for LUNs > 2 TB

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

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.)

Chapter 1: Installing StorNext File System and Storage Manager Pre-Installation Script

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

The StorNext support directories are described in Ta bl e 4.

Contains configuration files and support data required for disaster recovery.

Before You Begin 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?

8 StorNext 3.5.2.1 Installation Guide

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 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 5 running on an x86 64-bit platform, change to the

RedHat50AS_26x86_64 directory.

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

./snPreInstall

The pre-installation script runs (Figure 1).

6 Follow the onscreen instructions, and answer each question when

prompted.

The script outputs results based on the information you entered.

Interpreting snPreInstall Output

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.

Te c h T i p : 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 Installation Script

Table 5 Pre-Installation Script Recommendation Types

Typ e 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.

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

Disabling Automatic IP Address Configuration

26 StorNext 3.5.2.1 Installation Guide

Before installing StorNext, you should disable automatic IP address configuration in Windows. Disabling automatic IP address configuration

Chapter 2: Installing StorNext File System

Installing StorNext File System on Windows

ensures that the FSM passes the correct IP address to file system nameservers. Failure to disable automatic IP address configuration could result in StorNext clients or servers being unable to talk to the active FSM.

There are two methods for disabling automatic IP address configuration:

• Manually configuring the TCP/IP information, which disables DHCP. You should use this method if any static IP addresses have been configured.

• Editing the Windows registry to disable automatic IP address configuration but not disable DHCP. To use this method, follow the procedure outlined in Microsoft article 220874 available here:

http:/

/support.microsoft.com/kb/220874.

Removing a Previous Version of StorNext

If a previous version of StorNext older than version 3.0 exists on the system, you must remove it before installing the new version. If you are upgrading from a version of StorNext newer than version 3.0, the old client configuration is retained so there is no need to restore the old configuration.

1 Insert the StorNext installation CD.

2 Browse to the root directory of the installation CD and double-click

the file

SnfsSetup64.exe.

• 500 MB available hard disk space

For SAN clients acting as a distributed LAN server:

•2 GB RAM

• 500 MB available hard disk space

StorNext 3.5.2.1 Installation Guide 39

Chapter 3: Installing the StorNext Client Client System Requirements

Note: Distributed LAN servers may require additional RAM depending

on the number of file systems, distributed LAN clients, and NICs used. See

Distributed LAN Server Memory Tuning in the

StorNext User’s Guide for Distributed LAN Server memory tuning guidelines.

StorNext File System Client Buffer Cache

Table 12 Default Memory Consumed by cachebufsize

As of StorNext 3.0, multiple mounted file systems typically share a single buffer cache. A StorNext client buffer cache is created for each different

cachebufsize. By default, all file systems have the same cachebufsize of

64K, so they all share the same buffer cache.

Note: These settings do not apply to Apple Xsan clients, which do not

use the StorNext buffer cache.

The amount of memory consumed by default for each cachebufsize depends on the platform type and the amount of memory in the system.

cachebufsize.

Ta bl e 12 shows the default amount of memory consumed by

Platform Type <=2GB Memory >2GB Memory

32-bit Windows 32MB 64MB

32-bit Linux 64MB 128MB

All other platforms 64MB 256MB

To see information about the buffer cache after mounting file systems, use the memory used by the buffer cache at mount time, use the

cvdb(1) command with the -b option. To change the amount of

parameter.

On Windows, the non-paged pool is used for buffer cache memory until it consumes up to 64 megabytes (32-bit systems) or 64 gigabytes (64-bit systems). Any additional buffer cache memory comes from the paged pool.

Chapter 3: Installing the StorNext Client

Client Installation Changes From Previous Releases

Beginning with StorNext release 3.5.2.1, the delivery mechanism for client software has changed. Client software for all operating systems is now contained on one disk labeled “Client Software and Product Documentation.” (Formerly, client software was distributed on the software disks for all operating systems.)

You must now insert the client software disk, copy the client software from the disk, and then install or upgrade the client packages as described in this guide.

In addition, client software is no longer distributed in compressed format (such as tar.gz files). Instead, the client software disk contains executable files which, when launched, extract the client software for the selected platform to the location /tmp/stornext where you can install the package. Windows client packages have not changed, and are still in .zip format.

Following is a summary of the changed part of installation procedure for UNIX and Linux systems:

1 Log on to the client system as root.

2 Change to the directory where the client software archive file you

downloaded from the MDC is located.

3 Run the client software binary. At the command prompt, type:

./<archive name>

where <archive name> is the name of the software archive file you downloaded from the MDC. (For example, the file for RH5 is

sn_dsm_linuxRedHat50AS_x86_64_client.bin)

4 When you are presented with the StorNext End User License

Agreement (EULA), press <ENTER> to read the EULA. After reading the EULA enter y (lower case only) to accept the EULA, or enter any other key to decline.

After you accept the EULA, the client software is extracted to /tmp/stornext.

5 Change directories to /tmp/stornext.

6 Follow the remaining installation steps in Installing the StorNext

Client on Linux or Unix on page 45.

Configuring a Distributed LAN Client Server

Traditional StorNext SAN clients access data disks using a high throughput, low-latency fibre channel connection. In addition, using the distributed LAN client and server feature, StorNext clients can access data disks over a network instead of directly accessing disks.

A StorNext client running on Linux or Windows can be configured as a distributed LAN client or a distributed LAN server. (This is a licensed feature.)

68 StorNext 3.5.2.1 Installation Guide

Chapter 4: Configuring StorNext

Configuring a Distributed LAN Client Server

• Distributed LAN Server: A distributed LAN server has direct access to data disks (using fibre channel) and makes the shared storage pool available to distributed LAN clients over a network.

• Distributed LAN Client: A distributed LAN client does not have direct access to data disks and instead accesses the shared storage pool by connecting to a distributed LAN server over a network. (Distributed LAN clients have full StorNext client functionality.)

Note: A StorNext client configured as a distributed LAN server

requires a dedicated system. Do not run other applications or services on a system configured as a distributed LAN server.

To configure a Linux client as a distributed LAN client, see Configuring a

Distributed LAN Client on Linux. To configure a Linux client as a

distributed LAN server, see Configuring a Distributed LAN Server on

Linux.

To configure a Windows client as a distributed LAN server or a distributed LAN client, use the Windows Client Configuration utility. For more information, see

Client Configuration on page 74 and Distributed

LAN on page 76.

Configuring a Distributed LAN Client on Linux

To configure a StorNext client as a distributed LAN client, edit mount options in the

/etc/fstab file.

1 Stop the StorNext client. At the command prompt, type:

/etc/init.d/cvfs stop

2 Configure the client to mount a file system as a distributed LAN

client. To do this, edit the

/etc/fstab file so that it contains the

following line:

<file system> <mount point> cvfs rw,diskproxy=client 0 0

where <file system> is the name of the StorNext file system and

<mount point> is the directory path where the file system is mounted.

3 Start the StorNext client. At the command prompt, type:

Distributed LAN

The Distributed LAN tab is used to enable and configure StorNext Distributed LAN (DLAN) Clients and Servers for a file system. The Enable Client and Enable Server radio buttons determine whether the system is a Client or Server. Note that separate licensing is required for DLAN.

StorNext Distributed LAN Clients provide the same functionality as normal StorNext Clients but do not need to be connected directly to the SAN. They instead send I/O via the TCP/IP network to a Distributed LAN Server; a normal SAN client with DLAN Server Selected in its configuration. Metadata is sent over the TCP/IP network directly to the File System Metadata Controller (Server/MDC).

Distributed LAN Clients request the location of normal DLAN Servers via the Name Server.

• Distributed LAN Server: A distributed LAN server has direct access to data disks (using fibre channel) and makes the shared storage pool available to distributed LAN clients over a network.

Specify the number of times the driver will re-transmit a message to the FSM. After a successful connection, this value is no longer used.

The default is 1.

Hard Mount When this box is checked, the driver attempts

to mount the file system forever. The default is off (Soft Mount). Quantum

recommends that Hard Mount NOT be used on Windows systems.

Allow Diskless Mount When this box is checked, the file system can

be mounted and accessed without all the disks being accessible in the file system stripe groups. In this mode, file metadata can be viewed and changed, but no data can be accessed.

The default is to not allow a file system to be mounted unless all disks are accessible.

Read Only When this box is checked, the file system is

Retry I/Os Forever or Allow I/O

Timeouts

I/O Retry Time Seconds

I/O Penalty TIme Seconds

Choose either Retry I/Os Forever or Allow I/O Timeouts, depending on whether you want to allow timeouts or keep trying I/O. The default value is to Retry I/Os Forever.

When you choose Allow I/O Timouts, this option controls the I/O retry behavior. This parameter establishes the amount of time that may elapse during an I/O retry sequence.

An I/O retry sequence consists of the following:

• Retry an I/O request across all available paths that are currently present.

• Compare the current time to the Instantiation time of the I/O request, if at least <n> seconds have elapsed, return the I/O request in error, otherwise reset the paths used, and retry again.

This option controls the Multi-Path I/O penalty value, where <n> is expressed in seconds with a minimum value of 1 and a maximum value of 15.

This parameter establishes the amount of

time a Path_In_Error will be bypassed in

favor of an Operational Path during a MultiPath selection sequence. If all paths are currently in the Path_In_Error state, the first available path will be selected, independent of the Path_In_Error state.

The default value is 5 seconds.

StorNext 3.5.2.1 Installation Guide 81

Chapter 4: Configuring StorNext Windows Configuration Utilities

Field / Button Description

Fast Failover Detection

When this box is checked, the client uses a more aggressive approach to detecting if the FSM has failed. With this option on, the client monitors the FSM heartbeat. If no heartbeat is detected within three (3) seconds, a failover request is initiated.

This option is desirable for near realtime activities that cannot sustain more than 10 seconds of access loss to the server. Quantum does not recommend enabling this option for normal file system operations.

Hard Reconnect When this box is checked, the file system

attempts to reconnect to the FSM forever. If this option is not enabled, the file system attempts to reconnect to the FSM for the number of times specified at the Mount Retransmit Limit field before failing the request.

The default value is off.

Token Hold Seconds The QOS Token Hold Time parameter is

applicable only when using the StorNext Quality of Service (QOS) feature for real-time IO.

This parameter determines the number of seconds a client stripe group holds on to a non-realtime I/O token during periods of inactivity. If no I/O is performed on a stripe group within the specified number of seconds, the token is released back to the FSM.

The default value is 60 seconds. The parameter should be specified in five-second increments; if the parameter is not a multiple of five, it will be rounded up automatically.
