2. Ascertain the IP address of the management console (for example, using 
ipconfig in a DOS environement). Then change its IP address to 
192.168.0.
x where x is a number from 1 to 254, excluding 16 and 17. 
Write this IP address on a piece of paper. You will be prompted for it 
during the Storage Navigator Modular 2 installation procedure.
3. Disable popup blockers in your Web browser. We also recommend that 
you disable anti-virus and proxy settings on the management console 
when installing the Storage Navigator Modular 2 software.
4. To log in to Storage Navigator Modular 2 with a Red Hat Enterprise Linux 
(RHEL) operating system, modify the kernel settings as follows:
• SHMMAX parameter. This parameter defines the maximum size, in 
bytes, of a single shared memory segment that a Linux process 
can allocate in its virtual address space. If the RHEL default 
parameter is larger than both the SNM2 and Database values, you 
do not need to change it.
• SHMALL parameter. This parameter sets the total amount of 
shared memory pages that can be used system wide. For SNM2, 
this value must equal the sum of the default value, SNM2, and 
Database values.
• Other parameters. The following parameters follow the same rule 
as SHMALL and must be the higher of (RHEL current value + 
value in Navigator 2 column) or the value from the Database 
value.
• kernel.shmmni
• kernel.threads-max
• kernel.msgmni
• kernel.sem (second parameter)
• kernel.sem (fourth parameter)
•  fs.file-max nofile nproc

Firewall considerations
A firewalls main purpose is to block incoming unsolicited connection 
attempts to your network. If the AMS 2000 Family storage system is used 
within an environment that uses a firewall, there will be times when the 
storage system’s outbound connections will need to traverse the firewall.
The storage systems incoming indication ports are ephemeral, with the 
system randomly selecting the first available open port that is not being 
used by another Transmission Control Protocol (TCP) application. To permit 
outbound connections from the storage system, you must either disable the 
firewall or create or revise a source-based firewall rule (not a port-based 
rule), so that items coming from the storage system are allowed to traverse 
the firewall.
Firewalls should be disabled when installing Navigator 2 (refer to the 
documentation for your firewall). After the installation completes, you can 
turn on your firewall.
If you use Windows firewall, the Navigator 2 installer automatically registers 
the Navigator 2 file and Command Suite Common Components as 
exceptions to the firewall. Therefore, before you install Navigator 2, confirm 
that no security problems exist.
Anti-virus software considerations
Anti-virus programs, except Microsoft Windows’ built-in firewall, must be 
disabled before installing Navigator 2. In addition, Navigator 2 cannot 
operate with firewalls that can terminate local host socket connections. As 
a result, configure your anti-virus software to prevent socket connections 
from being terminated at the local host (refer to the documentation for your 
anti-virus software).
NOTE:For outgoing traffic from the storage system’s management port, 
there are no fixed port numbers (ports are ephemeral), so all ports should 
be open for traffic from the storage system management port.

Administrators group.
• Disable power management through Windows to prevent the host from 
entering suspension mode.
Selecting a destination folder
During the Navigation 2 installation, you are prompted to select a 
destination folder. You can accept the default destination folder or select a 
different destination folder.
If you select a different destination folder, be sure the folder complies with 
the following requirements:
• The folder name should only contain the characters A to Z, a to z, 0 to 
9, hash mark (#), plus sign (+), hyphen (-), period (.), at mark (@), 
underscore (_), and the space character.
• A space character cannot appear at the beginning or end of a folder 
name.
• The path name cannot contain any names reserved by the operating 
system (for example, CON, AUX, NUL, PRN, CLOCK$, COM1 to COM9, 
and LPT1 to LPT9).
• The path to the destination folder cannot exceed 100 characters.
• The path to the destination folder cannot be a route to a drive. 
Otherwise, the installer displays the following error message during the 
installation.

Solaris and Linux operating systems
Installation prerequisites
Before installing Navigator 2 on a management console running one of the 
supported Solaris and Linux operating systems in Table 2-3 on page 2-4:
• Log on as a root user.
•If /opt exists, the normal directory is required, not the symbolic link. 
However, the file system can be mounted as a mount point.
• For Solaris v10 (SPARC), apply the appropriate patch.
•  Apply patch 120664-xx (where xx is 01 or later).
•  Apply patch 127127-xx (where xx is 11 or later).
•  Do not apply patches 127111-02 and 127111-03.
• For Solaris v10 (x64), apply patch 120665-xx (where xx is 01 or later)
• For Linux, set the kernel parameters described in the following 
sections.
Setting Linux kernel parameters
To set the Linux kernel parameters:
1. Back up the kernel parameters setting files /etc/sysctl.conf and  
/etc/security/limits.conf.
2. Open the kernel parameters setting file /etc/sysctl.conf with a text 
editor and change the following settings. The parameters are specified 
using the syntax [name of parameter]=[value]. Four values separated 
by space are specified in kernel.sem. Your parameter settings must not 
exceed the maximum value for the operating system. 
The following example shows how to check whether the value is valid for 
kernel.shmmax:
cat /proc/sys/kernel/shmmax
Table 2-8 provides recommended values and calculation methods for 
each kernel type.
