Firmware requirements

Figure 1 RMI Conﬁguration: Save/Restore tab

Firmware with the features described in this document have a Conﬁguration: Save/Restore tab in the

remote management interface (RMI). You can always download the most current ﬁrmware ﬁles from

http://www.hp.com/support. See the User and service guide for instructions on updating ﬁrmware.

Network conﬁguration and IPv6

This Autoloader contains new network features, including support for Internet Protocol version 6 (IPv6),

DNS server conﬁguration, and secure HTTP access to the RMI. The remote management interface (RMI)

and operator control panel (OCP) menus have been updated to incorporate these new features.

IPv6 is a new version of the Internet Protocol, and is designed to be the successor to IPv4, the current

Internet Protocol. IPv6 provides more network addresses and adds many improvements to IPv4, especially

in routing and network autoconﬁguration. IPv6 is expected to gradually replace IPv4, with the two

protocols coexisting during that time. The Autoloader supports both protocols and you can conﬁgure the

Autoloader to use either or both, depending on your network requirements.

Enabling HTTPS access

HTTPS (Hypertext Transfer Protocol over Secure Socket Layer) provides authenticated and encrypted

transfer of data over the Internet and is frequently used for secure web communication. If operators or

administrators connect to the RMI over insecure networks, such as from home or a remote location,

enabling HTTPS will keep an outsider from viewing the RMI communication. You can enable HTTPS from

the RMI Conﬁguration: Network page.

Enabling IPv6 with the OCP

By default, the Autoloader is conﬁgured to use IPv4 with DHCP. If your network supports IPv4 and has a

DHCP server, you can ﬁnd the IP address of the Autoloader from the OCP. You may use that address

to access the RMI and conﬁgure IPv6. If the network does not have a DHCP server, set the IPv4 IP

address from the OCP before accessing the RMI.

To ﬁnd the IP address obtained from an IPv4 DHCP server from the OCP, use the Status/Information

> Network Information menu.

To set the IPv4 IP address, or disable IPv4 and/or enable IPv6, use the Configuration > Configure

Network Settings menu.

For additional information about network conﬁguration, see the current HP StorageWorks 1/8 G2 Tape

Autoloader Getting started guide, which you can download from the Manuals page of the HP Business

HP StorageWorks 1/8 G2 Tape Autoloader Addendum 3

Support Center website: http://www.hp.com/support/manuals. In the Storage section, click Tape

Storage and Media and then select your product.

Conﬁguring the network with the RMI

Once the Autoloader is accessible over the network, you can conﬁgure additional network features from

the RMI. Some network features, such as SNMP, HTTPS, and IPv6 can only be conﬁgured from the RMI.

Conﬁguration: Network

Use the Conﬁguration: Network page to see and modify the current network conﬁguration.

Figure 2 Conﬁguration: Network page

You may change the:

•Protocol Stack — selects the Internet Protocols that will be enabled. Select the IPv4 protocol, the

IPv6 protocol, or both IPv4 and IPv6 protocols. The default is the IPv4 protocol.

•Hostname — enter the hostname provided by your network administrator for the Autoloader.

•Domain name — enter the domain name provided by your network administrator for the

Autoloader.

•Enable HTTPS — When On, the RMI can only be accessed through an HTTPS connection.

For IPv4, you may change the:

•DHCP Address — When On, the Autoloader will request an IP address from a DHCP server each

timethedeviceisbooted. ThedefaultisOn.

•IPv4 Address — conﬁgures the IP address if DHCP is not enabled.

•Network Mask — conﬁgures the network mask of the autoloader controller if DHCP Address

is not On.

•Gateway Address — conﬁgures the gateway address if DHCP Address is not On.

•IPv4 DNS Server 1 and IPv4 DNS Server 2 — conﬁgures the addresses of up to two DNS servers

ifDHCPAddressisnotOn.

For IPv6, you may change the:

•IPv6 DNS Server 1 and IPv6 DNS Server 2 — conﬁgures the addresses of up to two DNS servers

if DHCPv6 is not enabled.

•Stateless Addressing Enabled — when On, the Autoloader will generate an address for itself

based on the routing information obtained from a router advertisement and the MAC address.

The Autoloader can manage up to ﬁve global addresses at the same time, which can be assigned

from different routers. The default is On.

•DHCPv6 Addressing Enabled — when On, the Autoloader will request an IP address from a

DHCP server each time the device is booted. The default is Off.

•Static Addressing Enabled — when On, the Autoloader will use a statically-conﬁgured address.

The default is Off.

•Static Assigned Address — conﬁgures the address when Static Addressing Enabled is On. You

can select the standard preﬁx, FE80:,orthepreﬁx of a nearby router. Enter the remainder of

the address and click Add.

To remove an IPv6 static IP address, click Delete next to the address in the Current IPv6 Addresses pane.

HP StorageWorks 1/8 G2 Tape Autoloader Addendum 5

Conﬁguration: Network Management

Use the Conﬁguration: Network Management page to enable and conﬁgure SNMP (Simple

Network Management Protocol), which allows applications such as HP Systems Insight Manager

(http://www.hp.com/products/SystemInsightManager) to manage the device. The device supports

both SNMP conﬁguration and SNMP traps. SNMP can only be conﬁgured with the RMI; it cannot

be conﬁgured with the OCP.

Figure 3 Conﬁguration: Network Management page

You may change the:

•SNMP Enabled — When checked, the device can be managed by computers listed in the SNMP

Target IP Addresses ﬁeld.

•SNMP Target IP Addresses — the IP addresses for up to three computers for IPv4 and three

computers for IPv6 running SNMP management software. IP addresses will not be cleared if

SNMP is disabled, but those targets will no longer be able to manage the Autoloader and will

not receive traps from the Autoloader. You can select the SNMP version for each target address.

•Community Name — a string used to match the SNMP management station and device. It must

be set to the same name on both the management station and the Autoloader. The default

community name is public.

•SNMP Trap Notiﬁcation Filter — the types of events for which the device should send SNMP traps.

For instructions on conﬁguring HP Systems Insight Manager for the Tape Autoloader, see the User and

service guide on the documentation CD.

Autoloader modes

The Autoloader supports three behavior modes: Random, Sequential, and Automatic. Choose the

operating mode based on the capabilities of the software controlling the tape cartridges.

Random mode:InR

andom mode, the device does not automatically load tapes into the tape drives; it

waits for commands from the software or operator to load and unload tapes. Random mode is used with

a full-featured or robotics-aware backup application and is the most common mode of operation. Your

backup software must support robotics, which may require an additional software module.

Sequential mode: In Sequential mode, the device automatically loads and unloads tapes from the tape

drive. Sequential mode is used when the backup software is NOT robotics aware or was designed for

standalone drives only.

The operator begins the sequence by loading the desired tape into the tape drive. When a tape is

unloaded for any reason, the device automatically removes the tape from the tape drive, returns it to its

original slot, and then loads the tape from the next available higher numbered slot.

To further determine how you want the tapes loaded into the tape drive while in Sequential mode, you

can set the Loop and Autoload options.

•When Autoload mode is set, the device automatically loads the cartridge from the

lowest-numbered full slot into the tape drive. It then follows standard sequential operation.

•When Loop mode is set, the original ﬁrst cartridge in the sequence is reloaded after the device

has cycled through all available cartridges. If Loop mode is not set and the last cartridge has

been unloaded, the device stops loading cartridges until you load another cartridge manually.

CAUTION:

Use caution when choosing Loop mode because it makes it possible to overwrite data on previously

written cartridges.

Automatic mode: In Automatic mode, the device switches from Sequential mode into Random mode when

it receives certain SCSI commands. Automatic mode is the default setting.

Saving and restoring the Autoloader conﬁguration

You can save the Autoloader conﬁguration database to a ﬁle or USB ﬂash drive. The saved conﬁguration

database will make it easier to recover the Autoloader conﬁguration if you need to replace the chassis.

This feature is also useful when installing multiple Autoloaders. Either save the conﬁguration before

conﬁguring the network or ensure that only one device with the same network conﬁguration is on the

network at a time until they have unique network identities.

Use the RMI Conﬁguration: Save/Restore tab to save the conﬁguration database to a ﬁle or restore it

from a ﬁle.

Use the OCP Support > Save Config menu item to save the conﬁguration database to a USB ﬂash

drive. Use the OCP Support > Restore Config menu item to restore the conﬁguration database

from a USB ﬂash drive.

Wellness test

The Wellness test exercises all Autoloader and tape drive hardware, except the external connections, and

is useful for verifying that a device is working correctly. The Wellness test requires operator interaction

with the mailslot so cannot be initiated from the RMI.

For complete testing, enable the mailslot and ensure that each corner slot contains a tape cartridge. The

corner slot positions , as shown below, are: M1, 3, 4, and 7.

IMPORTANT:

TheAutoloaderwillremoveanytapecartridgesfromthetapedrivesandgoofﬂine when running

the Wellness test. Verify that any applications using the Autoloader have completed before starting

the Wellness test.

You can have the Autoloader run up to 10 cycles of the Wellness test.

The Wellness test requires operator interaction and can only be run from the OCP. During the Wellness test:

1. The operator starts the Wellness test from the OCP. The administrator password is required.

2. TheAutoloaderperformsaselftestandveriﬁes that it can communicate with the tape drive.

3. The Autoloader returns the tape cartridge in the tape drive to its home slot, if necessary. If the

home slot is not known, the Autoloader will move the cartridge to the mailslot and prompt

the operator to remove it.

4. The Autoloader prompts the operator to enter the number of cycles to run the test.

5. The Autoloader opens the mailslot and prompts the operator to insert a scratch cartridge.

6. The operator inserts a scratch cartridge into the mailslot. If the mailslot is disabled or the

operator closes the mailslot without inserting a cartridge into the mailslot, the Autoloader will

perform a shortened version of the Wellness test, skipping step 7.

7. The Autoloader loads the scratch cartridge into the tape drive, unloads the scratch cartridge from

the tape drive, and returns the scratch cartridge to the mailslot.

8. The Autoloader moves the tape cartridge from the four top-row corner slots to the tape drive load

point and then returns the tape cartridge to its slot. If one of the top-row corner slot positions

does not contain a tape cartridge, the Autoloader will skip that location. If none of the top-row

corner slots contain a tape cartridge, the Autoloader displays an error message.

9. If additional cycles remain to be run, the test will return to step 7 if there is a tape cartridge in

the mailslot or step 8 if there is not a cartridge in the mailslot.

10. At the conclusion of the test, the Autoloader pops open the mailslot and waits for the operator

to remove the scratch tape.

11. The Autoloader displays the test completion status, including any recoveries or errors that may

have occurred.
