This section covers installation of the Dell PowerVault 136T SNC, SCSI devices,
and the host bus adapter.
Pre-Installation
To ensure a successful installation of the SNC, verify the items in the following
list before you begin the installation.

1
Verify host platform operating system required Service
Pack installed. For example: Microsoft® Windows NT® 4.0, Service
Pack 6a (or later)
For a current list of supported platforms required host
platform code updates and information on how to obtain them, visit support.dell.
com.
2
Verify required FC HBA, HBA BIOS, and device driver
are procured and installed.
For a list of supported HBAs and the required BIOS and
device driver, visit support.dell.com.
3
Ensure that all host FC cables:
Have been ordered with the product or have been pre-installed and
checked.
Are marked with:
Host system identifier
Library system identifier
See the HBA Specification provided with
your HBA.
4
Mark both ends of each SCSI cable with the drive ID and
SNC connector number.
None.
5
Decide on network parameters. Ethernet
port configuration decisions:
Static IP address____________
Netmask (if required)_________
User-defined tape library name (optional)__________________
If the tape library is not on the same TCP/IP subnet as the server, assign
the default network gateway address and/or route table entries. ________________________
NOTICE: Save this configuration information
for future reference.
Obtain the network
parameters from your network administrator.
NOTICE: Use of incorrect network parameters
can cause problems on the Ethernet network.
The default network name is SNC. If you choose a different name, it becomes
the prompt displayed on the service terminal. Choosing a different name
may be useful if you have more than one tape library.
Installation
The procedure below instructs you on how to install the SNC. You may have
the option of having a Dell service technician perform this portion of the
installation
for you.
Acquire information for Ethernet installation.
Insert the SNC in the empty bay of the tape library. Align the power connector
and seat unit firmly. Tighten the two thumbscrews. See Figure

Configuring the SNC
This section provides information for configuring your tape library for use
in a SAN.
NOTICE:
To ensure proper initialization of your SNC, always allow at least
one minute between a tape library power-down and subsequent power-up.
Connect with HyperTerminal to the SNC using a null-modem cable. Use the
following settings:
Baud: 19,200
Data bits: 8
Parity: None
Stop bits: 1
Flow control: None
Power on the tape library and observe the startup messages in HyperTerminal.
The SNC will complete initialization and display a command prompt in the form
of the serial number and a '>' (ex: 600023 >)
when it is ready to receive commands.
Issue the initializeBox command. This will
require a reboot of the tape library.
Once the tape library has finished rebooting, verify your cable connections
from the SNC to your SCSI devices by typing scsiShow.
Match your actual SCSI connections with the data provided from scsiShow.
If a device fails to appear, verify the installation of all your cable connections
and terminators.
Set the IP address for the SNC 6101 using the following command: ethAddrSet "ip_address","subnet_mask"
where "ip_address" and "subnet_mask"
are replaced with actual values (for example: ethAddrSet
"192.168.1.2","225.225.225.0").
Verify that your IP address was entered correctly by typing ethAddrGet.
A typical response would be: IP Address set to 192.168.1.2:fffff800
where "192.168.1.2" is the address
just assigned, and "fffff800" is the
subnet mask displayed in hexadecimal.
Set the gateway address for the SNC 6101 using the following command: gateAddrSet "default_gateway_ip"
where "default_gateway_ip" is replaced
with the default gateway IP address (for example 192.168.1.1).
Verify that your gateway address was correctly entered by typing gateAddrGet.
A typical response would be: gateway Address set to
192.168.1.1
Set your host name using the following command: hostNameSet "name"
where "name" is replaced with the name
you would like displayed in the SAN Library Manager.
The default network name is the serial number of the unit. The host name always
appears in the service terminal’s prompt. For easy recognition, provide
a name that readily identifies itself with the name assigned to the tape library.
Verify that this host name now appears in the command line prompt.
Set the date and time using the following command: rtcDateSet
[year], [month], [day], [day of week], [hour], [minutes], [seconds]
A typical entry would be: rtcDateSet 2003, 5, 25, 4,
3, 47, 00
for May, 25th, 2003; Wednesday, 3:47:00
You can also set the real-time clock using a timeserver. See the setNettime
command.
After setting the date and time with the rtcDateSet
command, use dateSetFromRTC to set the real-time
clock as the source of the date display.
Rebuild the SNC database and initiate a reboot by typing mapRebuildDatabase.
Cable the SNC to the SAN. The recommended cabling configuration to a SAN
is depicted in Figure 10.
Figure 10. SNC Cabling to SAN
Reboot the tape library. (To ensure proper initialization of your SNC,
always allow at least one minute between a tape library power-down and subsequent
power-up.)
Start the SAN Library Manager server application. This application is found
on the Start Menu under Start-> Programs->
Dell PowerVault SNC Manager-> Server.
Start the SAN Library Manager client application. This application is found
on the Start Menu under Start-> Programs->
Dell PowerVault SNC Manager-> Client.
Restart the tape library.
It may be necessary to configure your host-based logical unit number (LUN)
management software to access the tape library.
Other Installation Issues
After you have completed installation, check the following items before using
your SNC.
Power-Up and Boot Sequence Guidelines
Before you reboot the tape library, you must stop all I/O between the host and
SCSI devices.
The SNC scans the SCSI buses when it boots. If you add or remove SCSI devices
after the tape library has booted, it will not detect the changes.
Before you turn on or restart the hosts that are connected via FC to the
tape library, you must wait until the SNC has finished booting. You will
know that
the SNC has finished booting when the RDY LED on the control panel blinks
at intervals of one second.
Some operating systems provide you with software methods that allow you
to add or remove SCSI devices dynamically after the host has booted. To ensure
reliable operation, reboot the host.
If you update SNC firmware, you must reboot in order to use the new firmware.
To ensure compatibility between the firmware features or functions and the
host, reboot the host.
If you update SCSI device firmware, the SAN Library Manager client application
and the service terminal do not display the new firmware version until the
SNC has issued a SCSI inquiry. The SCSI inquiry occurs when it rescans the
SCSI buses.
SNMP
The SNC implements an SNMP agent to communicate with the firmware. To customize
the SNC's SNMP configuration, refer to the snmpHelp
command.
