Regulatory Information

FCC-15 User Information

The V-Switch has been tested and found to comply with the limits of the
Class A digital device, pursuant to Part 15 of the FCC rules. These limits are
designed to provide reasonable protection against harmful interference
when the V Switch is operated in a commercial environment. The V Switch
generates, uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instruction manual, may cause harmful
interference to the radio communications. Operation of the V Switch in a
residential area is likely to cause harmful interference in which case the user
will be required to correct the interference at the user’s own expense.

Warning per EN 55022

The V-Switch is a Class A product. In a domestic environment, this product
may cause radio interference, in which case the user may be required to
take adequate measures.

SANRAD V-Switch CLI User Manual

Safety Notices

Read and understand the following notices before installing the V-Switch.

The power plug must be accessible at all times because it serves as the main
disconnecting vehicle.

Unplug the V-Switch power cord before performing maintenance procedures.

The V-Switch contains two power supply units. To disconnect the V-Switch
completely, all power supply cords must be unplugged.

Do not touch the power supplies when their power cords are connected. Line
voltages are present within the power supplies when their cords are connected.

The safety cover is an integral part of this product. Do not operate the unit without
the safety cover firmly in place. Operating the unit without the cover in place will
invalidate the safety approvals and pose a risk of fire and electrical hazards.

Blank faceplates and cover panels serve three important functions: they prevent
exposure to hazardous voltages and currents inside the chassis; they contain
electromagnetic interference (EMI) shields that might disrupt other equipment; and
they direct flow of cooling air through the chassis. Do not operate the system
unless all cards and faceplates are in place.

This product relies on the building’s wiring for short-circuit (overcurrent) protection.
Ensure that a fuse or circuit breaker no larger than 120 VAC, 15a U.S. (240 VAC, 10A
international) is used on the phase conductors (all current-carrying conductors).

The V-Switch is intended to be grounded. Ensure that the V-Switch is connected to
earth ground during normal use.

When installing the V-Switch, the ground connection must always be connected first
and disconnected last.

There is a danger of explosion if the motherboard battery is replaced incorrectly.
Replace the battery with the same or an equivalent type as recommended by the
manufacturer. Dispose of the used battery according to the manufacturer’s
instructions.

Assistance

The V-Switch is a storage virtualization and management solution
that allows you to pool physical storage resources and re-partition
the total storage capacity into virtual volumes that best meet your
storage needs.

The V-Switch is a high performance appliance that operates in the
data-path of a storage network between the hosts and storage sub­system. It provides a single, easy-to-use connectivity and
management platform for administration of small to Enterprise
class storage resources.

The V-Switch enables a network administrator to create and
manage virtual storage volumes using SANRAD’s Volume
Manager. The Volume Manager supports the creation and
combination of concatenated, striped (RAID 0) and mirrored
(RAID 1) volumes.

V-Switch

1

The Volume Manager provides for secure exposure of virtual
volumes to hosts using the standards-based iSCSI TCP/IP-based
protocol.

Chapter 1: V-Switch 1-1

V-Switch Overview

The V-Switch provides protocol bridging, routing, switching and volume
management in a single platform.

Figure 1-1, details a standard V-Switch network topology. Two V-Switches sit
in the center of the network, providing load balancing and failover ability.

Above the V-Switches are IP clouds connecting the network(s) management
and host stations. The hosts can connect to the V-Switch directly or via an IP
cloud. An iSCSI initiator agent in the host allows access to virtual volumes in
the V Switch.

Below the V-Switches are the network storage devices, which include both
JBOD (Just a Bunch Of Disks) and RAID subsystems. The V-Switch provides
the ability to connect via both SCSI and FC protocols, including FC clouds,
increasing the number of potential attached storage devices.

The V-Switch can be used in two modes:

 iSCSI bridging switch
 Storage virtualization switch

End-to-end Fibre Channel protocol networks are expensive to implement. As
an iSCSI bridging switch, the V-Switch acts as a protocol bridge between
storage devices on a Fibre Channel network and hosts on a standard IP
network.

The V-Switch also acts as a protocol bridge between SCSI storage devices and
hosts on a standard IP network.

Simple exposure of each storage device as a single LUN is an inefficient use of
storage resources. As a storage virtualization switch, the V-Switch enables
barrier-independent storage pooling with precise LUN carving of new virtual
volumes which support mirroring and striping with managed exposure.

Surface Mounting

The V-Switch 2000 chassis is manufactured with four chassis feet. The V-Switch
2000 is ready to be mounted on any secure flat surface. If you plan to rack
mount the V-Switch 2000, continue with “Rack Mounting.”

Rack Mounting

The V-Switch 2000 chassis can be mounted on a 19-inch rack. The V-Switch
2000 can be mounted alone or two V-Switches can be joined and mounted
together in a single 1U space.

The V-Switch 2000 is shipped with an accessory packet of hardware. This
packet includes four non-identical L-brackets and twelve bracket screws for
rack mounting

You need the following tools to rack-mount the V-Switch 2000:

 A Philips screwdriver suitable for L-bracket screws
 Four rack-post screws (and clips if necessary) suitable for the

equipment rack

 A screwdriver suitable for the rack-post screws

Remove the rubber feet from the bottom of the V-Switch before beginning the
rack mount to ensure a proper fit in the rack enclosure.

Chapter 2: Installing the V-Switch 2000 2-5

STEP 1. PLACE THE V-SWITCH 2000 RIGHT SIDE UP ON A SECURE FLAT

SURFACE NEAR THE RACK

STEP 2. ATTACH THE LEFT FRONT L-BRACKET

The left front L-bracket is the wide L-bracket with two round openings for
air intake.

Attach it with four of the included screws. The bracket sits directly against
the V Switch.

STEP 3. ATTACH THE RIGHT FRONT L-BRACKET

There are two types of right front L-brackets, depending on if the V-Switch
is single or dual-mounted.

For single-mounting, use the long arm L-bracket to span the space from the
V-Switch to the rack. Attach it with four of the included screws.

For dual-mounting, use the short L-bracket on both V-Switches. Then place
the two V-Switches side by side with the lip of the left V-Switch L-bracket in
front of the lip of the right V-Switch L-bracket. Attach the two V-Switches
by inserting two screws through the front holes of the overlapping L­brackets.

STEP 4. ATTACH THE REAR L-BRACKET

If a single V-Switch is being mounted, attach the rear L-bracket to the left
side of the V-Switch.

If dual V-Switches are being mounted, attach a second rear L-bracket to the
right side of the right V-Switch as well.

STEP 5. ATTACH THE V-SWITCH 2000 TO THE RACK MOUNTING POSTS

Insert the rear of the V-Switch 2000 between the rack mounting posts until
the L-bracket(s) touch the rack mounting posts.

Align the mounting holes on the rear L-brackets with the mounting holes on
the rack mounting posts.

Using screws that you provide, attach the V-Switch 2000 to the rack
mounting posts by screwing two screws on each side through the L­brackets and into the threaded holes in the rack mounting posts.

Once the V-Switch 2000 is mounted, you can begin connecting the requisite
cables.

2-6 SANRAD V-Switch CLI User Manual

Storage Port Connections

Connect the SAN storage devices or fabric to the V-Switch 2000 using the
FC/SCSI storage ports.

The storage ports are located on the front right of the V-Switch 2000. The type
of storage ports on your V-Switch 2000 will vary depending on your V-Switch
2000 order specifications – either two SCSI or two FC ports.

The V-Switch 2000 contains a storage auto-discovery function. At power­up the V-Switch 2000 automatically scans for and registers all attached and
powered up network storage devices.

If you are building a V-Switch 2000 cluster, power up each disk one at a
time after connecting them to the powered-up V-Switches. This allows
each disk to be numbered with the same default disk number on each V­Switch 2000 during auto-discovery. This will make cluster configuration
easier. For more information on V-Switch 2000 clusters, see “V-Switch
Cluster Configuration”.

When connecting more than one V-Switch 2000 to a group of storage devices,
ensure that the same port on each V-Switch 2000 is used to connect to the same
storage device. This increases the chance of the storage device receiving the
same default storage number on both V-Switches during their auto-discovery
cycles. This, in turn, makes cluster configuration easier.

There are two FC storage port LEDs labeled lnk, one to the left of each storage
port.

Network Port Connections

The copper network ports, labeled Eth 1 and 2, are located on the front left of
the V-Switch 2000. Use the 1Gb Ethernet ports to connect to the network or
directly to the host station.

When configuring your network topology, keep in mind that the current
initiator technology does not support volume access by more than one server at
a time. There are two methods for allowing multi-server access to a volume:

 Connect a single server to the V-Switch 2000 and allow other server to

access the volume via file sharing.

 Install volume-sharing software to coordinate the read/write

functionalities and data synchronization between servers.

The network ports support all of the following:

Surface Mounting

The V-Switch 3000 chassis is manufactured with four chassis feet. The V-Switch
3000 is ready to be mounted on any secure flat surface. If you plan to rack
mount the V-Switch 3000, continue with “Rack Mounting.”

Rack Mounting

The V-Switch 3000 chassis can be mounted on a 19-inch rack.

The V-Switch 3000 is shipped with an accessory packet of hardware. This
packet includes two L-brackets, two rear mounts (one left and one right)
and ten bracket screws for mounting the L-brackets.

You need the following tools to rack-mount the V-Switch 3000:

 A Philips screwdriver suitable for L-bracket screws
 Eight rack-post screws (and clips if necessary) suitable for the

equipment rack; four for the front mounts and four for the rear mounts

 A screwdriver suitable for the rack-post screws

Remove the rubber feet from the bottom of the V-Switch before beginning the
rack mount to ensure a proper fit in the rack enclosure.

3-4 SANRAD V-Switch CLI User Manual

STEP 1. ATTACH THE REAR MOUNTS

Using screws that you provide, attach the rear mounts to the back
mounting posts so that the length of each mount is parallel to the floor and
extends forward into the rack space.

The lip of each mount is at the bottom and facing inward toward the
opposite rear mount.

The rear of the V-Switch 3000 will be supported from underneath on these
lips.

STEP 2. PLACE THE V-SWITCH 3000 RIGHT SIDE UP ON A SECURE FLAT

SURFACE NEAR THE RACK

This step works best

with two people.

STEP 3. A

TTACH THE L-BRACKETS ON BOTH SIDES OF THE CHASSIS

Use the ten screws included in the accessory packet to attach the L­brackets to the chassis.

STEP 4. INSERT THE V-SWITCH 3000 INTO THE RACK

This step works best with two people: one at the rear of the rack coordinating
the V-Switch/mount connection and one at the front of the rack inserting the V­Switch.

Slide the V-Switch 3000 into the rack making sure to position the V-Switch
3000 to rest on the rear mounts.

The rear mounts may turn inward slightly before the V-witch 3000 is
inserted. If the V-Switch does not enter easily, push the mount lips
outward slightly while inserting the V-Switch 3000.

Insert the rear of the V-Switch 3000 until the L-brackets touch the rack
mounting posts.

STEP 5. ATTACH THE V-SWITCH 3000 TO THE RACK MOUNTING POSTS

Align the mounting holes on the L-brackets with the mounting holes on the
rack mounting posts making sure that the L-brackets are the same height
as the rear mounts.

Using screws that you provide, attach the V-Switch to the rack mounting
posts by screwing two screws on each side through the L-brackets and into
the threaded holes in the rack mounting posts.

Once the V-Switch 3000 is mounted, you can begin connecting the requisite
cables.

Chapter 3: Installing the V-Switch 3000 3-5

Storage Port Connections

Connect the SAN storage devices or fabric to the V-Switch 3000 using the
FC/SCSI storage ports.

The storage ports are located on the back upper left of the V-Switch 3000. The
number and configuration of storage ports on your V-Switch 3000 will vary
depending on your V-Switch 3000 order specifications.

The V-Switch 3000 contains a storage auto-discovery function. At power­up the V-Switch 3000 automatically scans for and registers all attached and
powered up network storage devices.

If you are building a V-Switch 3000 cluster, power up each disk one at a
time after connecting them to the powered-up V-Switches. This allows
each disk to be numbered with the same default disk number on each V­Switch 3000 during auto-discovery. This will make cluster configuration
easier. For more information on V-Switch clusters, see “Introduction to V­Switch Clusters,” page 74.

When connecting more than one V-Switch 3000 to a group of storage devices,
ensure that the same port on each V-Switch 3000 is used to connect to the same
storage device. This increases the chance of the storage device receiving the
same default storage number on both V-Switches during their auto-discovery
cycles. This, in turn, makes cluster configuration easier.

Network Port Connections

The network ports, labeled Eth 1, 2 & 3, are located on the front right of the V­Switch 3000. Use the 1Gb Ethernet ports to connect to the network or directly
to the host station.

Each network port has both a fiber optic and copper connector but only one
cable, either fiber optic or copper, can be connected to each port. To connect a
fiber-optic cable you need a Small Form Factor Package (SFP) optical
transceiver to couple to the fiber optic cable and insert into the network SFP
port. Please refer to Figure 3-6.

The presence of an SFP will automatically determine which mode is active.

port.

Once the port is active in one mode, it will not change modes unless the
first, active connection is broken first. This means that once the port is
active over a copper connection, the insertion of an SFP optical transceiver
into the fiber optic connector will not change the port activity to fiber
optic. The copper connection must first be broken and then the fiber optic
connection made.

Conversely, if a port is active on a fiber optic connection and you want to
switch to copper, it is not enough to remove the fiber optic connection
from the SFP optical transceiver. The SFP optical transceiver must also be
removed from the fiber optic connector. Only then can the port activity
switch to a copper connection.

When configuring your network topology, keep in mind that the current
initiator technology does not support volume access by more than one server at
a time. There are two methods for allowing multi-server access to a volume:

 Connect a single server to the V-Switch 3000 and allow other servers to

access the volume via file sharing.

 Install volume-sharing software to coordinate the read/write

functionalities and data synchronization between servers.

3000. The scalability port is a V-Switch 3000 interconnectivity port. Using
SANRAD’s proprietary scalability cable, two V-Switches can be connected and
synchronized to function as one V-Switch 3000 to provide resource sharing and
computational power increase.

Powering Up

You can power up the V-Switch 3000 once you have connected and powered up
the storage devices. The V-Switch 3000 contains a storage auto-discovery
function. At power- up the V-Switch 3000 automatically scans for and registers
all attached and powered up network storage devices. Therefore, power up all
storage devices before powering up the V-Switch 3000. Storage devices added
after V-Switch 3000 power- up will be registered in the next V-Switch 3000
storage network scan.

The V-Switch 3000 contains two removable auto-switch 100V/230V AC
redundant power supplies.

After the V-Switch is connected properly to the physical disks,
management station and the network and powered up, the V­Switch must be configured.

The basic V-Switch configurations define the management IP
configurations and can be done either via the LCD panel for the V­Switch 3000 or the RS232 console port for both the V-Switch 3000
and the V-Switch 2000.

Once the management port is configured, any other V-Switch
configuration can be executed through the management port or
continued through the RS232 console port.

Disks and LUNs connected to the storage ports are discovered and
registered automatically.

Chapter 4: V-Switch Configuration 4-1

Introduction to Managing the V-Switch

After powering up the V-Switch, the first thing you must do is to configure its
management parameters. This can be done via telnet, SSH, using the V-Switch
LCD panel (for V-Switch 3000 only) or via a console or dumb terminal to open a
direct connection with the V-Switch’s RS232 console port.

The V-Switch can be managed in one of three different ways. Each way requires
a different configuration.

 Out-of-band

The management terminal (Telnet, SSH, SP server) connects to the V­Switch’s dedicated 10/100 management port via a fast Ethernet
network (refer to A, Figure 4-1). The V-Switch’s default IP
(10.11.12.123) can be used to connect to the V-Switch from remote (via
telnet).

 In-band

The management terminal (Telnet, SSH, SP server) connects to the V­Switch’s Eth1 port. The Eth1 port is used by the V-Switch for
management as well as by the hosts for accessing data accessing
storage data (refer to B, Figure 4-1).

 RS232

The console connects to the V-Switch’s RS232 port in a direct
connection (refer to C, Figure 4-1). The RS232 port is used mainly for
initial configuration: setting up the management IP, Mask and V­Switch name.

Changing the Telnet Communications Port

If your Telnet communications connection to the V-Switch traverses a firewall,
the standard Telnet communications port 23 may be blocked by the firewall as a
security measure. To enable Telnet communications to the V-Switch, you can
designate an alternate port using the CLI command device set -telnet.
This port can be opened in the firewall for dedicated Telnet-V-Switch
communications.

device set -telnet

Example:

The port 1597 is programmed as the Telnet communications port.

device set -telnet 1597

Use the CLI command info to check the V-Switch’s designated Telnet port.

Traps and SNMP

The V-Switch supports standard MIB s for monitoring and sends SNMP traps
that can be viewed by an SNMP manager/console. Any SNMP manager using
the correct default read and write communities can get and set MIB variables.
If you are working with StoragePro, the V-Switch GUI management system,
StoragePro will automatically add itself as the SNMP manager. The default
SNMP communities are public for read and private for write. The default
communities can be changed by an administrator.

Adding an SNMP Manager

To get trap notifications, an SNMP manager must be registered as a SNMP
manager in the database of the SNMP agent. You can register as a SNMP
manager by using CLI command snmp manager add.

snmp manager add

Discovering iSCSI Targets

iSCSI target discovery is performed across the IP-SAN by the iSCSI initiator
located on the server. The V-Switch supports three methods for reporting iSCSI
targets in the IP-SAN to iSCSI initiators:

 iSCSI Discovery Session
 SLP
 iSNS

iSCSI Discovery Session

The V-Switch supports iSCSI discovery sessions for reporting iSCSI targets to
iSCSI initiators. A V-Switch network IP address must be configured on the
iSCSI initiator for the initiator to connect to and discover the V-Switch’s
attached iSCSI targets.

SLP

The V-Switch supports Service Location Protocol (SLP) by acting as an SLP
Service Agent (SA). No configuration is necessary. An SLP SA services User
Agents (UAs). UAs are iSCSI initiators that query a network for all attached
iSCSI targets. The V-Switch supports the specific service service:iscsi:target.

Chapter 4: V-Switch Configuration 4-17

iSNS

The V-Switch supports Internet Storage Name Service (iSNS) protocol for
advertising its targets and portals on the iSNS server to enable iSCSI initiators
in the IP-SAN to locate the V-Switch targets automatically. Use the CLI
command ip isns add to add an iSCSI server to the V-Switch’s iSNS client.
Targets defined by the V-Switch’s Access Control List (ACL) as having
controlled access are accessible only to those servers defined as having access to
the target. See “Volume Exposure & Security”.

Configuring iSCSI Portals

Do not create an

iSCSI portal on the

management IP

address.

The V-Switch

supports a maximum

of 100 portals.

To enable communication between iSCSI initiators and iSCSI targets you
need to assign a portal to the iSCSI protocol transport. Use the CLI
command iscsi portal create to create an iSCSI portal. A portal is
the coupling of an IP address and a TCP port. Once created, a portal is
opened automatically during a communication session. If you are
working in a V-Switch cluster, each portal must be created on both V­Switches in the V-Switch cluster. For more information on V-Switch
clusters, see “Introduction to V-Switch Clusters”.

Discovery of iSCSI Storage Devices

An iSCSI device can have many portals. Each portal can have remote targets
associated with it. In order for the V-Switch to recognize a portal’s remote
targets, you must define the IP Address of the iSCSI portal. Once defined, the
V-Switch will automatically receive the list of remote targets attached to the
portal.

Configuring IP Routing

To enable communications between the V-Switch and IP networks located
outside the V-Switch LAN, you must configure IP routing paths for each
external network port. The IP route begins with a specified network port on the
V-Switch and ends at the external network IP address. Just as each IP address
is unique, each IP routing path is unique. There can be only one IP route to a
given external network IP address per V-Switch.

In Figure 4-6, you have two V-Switches connected to three different LANs (A,
B, C). In turn, each LAN is connected to at least one external network (D, E, F).

On V-Switch 1, network ports Eth1 and Eth2 can both access Network D:

PORT LAN ROUTER LEG
ETH1 A 20.20.10.20
ETH2 B 30.30.20.20

Only one of these paths can be configured for V-Switch 1.

Adding an IP Route

You can enable communications to networks outside of your LAN by
configuring an IP routing path. This allows volume access to hosts located on
external networks. Use the CLI command ip route add to add an IP routing
path to your V-Switch. If you are working in a V-Switch cluster, you must
configure the IP route on both V-Switches in the V-Switch cluster. For more
information on V-Switch clusters, see “Introduction to V-Switch Clusters”.

Managing a Cluster

V-Switch Cluster Configuration

You can configure a V-Switch cluster using two V-Switches of the
same type. A cluster is a group of storage units and switches that
function as one unit for virtualization and provide high
availability in the event of V-Switch failover.

A cluster can be configured between two V-Switches using CLI or
SANRAD’s StoragePro management GUI. We recommend using
StoragePro for its simplicity of use, particularly for cluster
configuration. For more information on configuring a cluster
using StoragePro, consult the StoragePro User Manual and on-line
help system. If you prefer to use CLI, continue with this chapter.

If your network still contains only one V-Switch, you can skip this
chapter and continue with Chapter 7 “Volume Exposure &

Security”.

Chapter 5: V-Switch Cluster Configuration 5-1

Introduction to V-Switch Clusters

Two V-Switches can be concurrently connected to the same storage devices to
balance volume exposure thus creating a V-Switch cluster. In a cluster, each V­Switch interacts in an active-active, peer-to-peer fashion with the other V­Switch, or neighbor, in the cluster. No one V-Switch must be configured
specially to act as the master V-Switch in the cluster providing higher flexibility
in building a cluster.

All virtual volumes are accessible to each V-Switch and the exposing V-Switch
is defined per volume.

In Figure 5-1, two V-Switches are connected to one JBOD. From the four
physical disks, two virtual volumes have been created, both equally accessible
to both V-Switches.

SANRAD V-Switches

are both fully

operational in a

cluster. No V-Switch

must sit in stand-by

mode.

Both V-Switches are also connected to two hosts via the IP SAN. The
volume exposure of the two virtual volumes is balanced equally between
the two V-Switches. Volume 1 is exposed via V-Switch 1 to Host 1,
represented by the orange dashed line. Volume 2 is exposed via V-Switch
2 to Host 2, represented by the purple dotted line.

The volume exposure is balanced equally between the two V-Switches
with one volume exposed on each V-Switch for best resource utilization.

When working in a

cluster, the V-Switch

can support a

portals: 50 active

and 50 inactive.

Clusters also provide high availability in the event of V-Switch failover.
Each network port on the V-Switch is configured with its own active, or
functioning, IP addresses as well as inactive, or dormant, neighbor IP
addresses. If one V-Switch goes off-line, the remaining V-Switch activates
its neighbor’s IP addresses. The hosts continue to access volume targets
through the same IP address without sensing that their ‘regular’ V-Switch
has gone offline or noticing any impact on storage performance.

When working with RAID controllers, it is imperative that all LUNs in the

RAID controller are simultaneously exposed through all ports connected
to both V-Switches for the V-Switches to provide high availability during a
V-Switch failover.

In Figure 5-2, V-Switch 1 has gone off-line. V-Switch 2 activates V-Switch 1’s IP
address and takes over exposure of Volume 1 to Host 1, represented by the
orange dashed line.

Host 1 continues to access Volume 1 through the same IP address as it did
before its V-Switch went off-line. Host 1 has no way of knowing that its regular
V-Switch is off-line. Host 1’s storage performance is not impacted by the off­line V-Switch.

When you configure a cluster, you must tell each V-Switch that it has a
neighbor and how to contact its neighbor. Use the CLI command
neighbor add to inform each V-Switch of its neighbor.

You must inform each V-Switch of its neighbor in a cluster. That means
that you must tell V-Switch 1 of V-Switch 2 and V-Switch 2 of V-Switch 1.

When creating a cluster, first ensure that you have configured all IP addresses
in the correct active/inactive phase as well as portals and IP routes on both V­Switches. For more information on configuring the V-Switch, see Chapter 4 “V-

Switch Configuration”.

Working with SCSI Storage Devices

The V-Switch default SCSI bus ID is 7. If your storage cluster includes SCSI
storage devices, one of the V-Switch’s default SCSI bus ID may need to be
changed, depending on the number of internal bus drives in the attached SCSI
storage system. Consult your SCSI system manual to verify if your SCSI device
has one or two internal buses. If your SCSI device has one internal bus, both V­Switches in the cluster will be sharing the same bus. Therefore, you have to
change the SCSI bus ID of one of the V-Switches. The V-Switch SCSI port also
includes a SCSI bus terminator. If both V-Switches are on the same SCSI bus,
you need to eliminate the storage device internal terminator, if present.

Use the CLI command pscsi set busid to change the SCSI bus ID on one
of the V-Switches.

Maintaining Cluster Communications

Once a V-Switch knows that it has a neighbor, it begins sending out a regular
keep alive signal to its neighbor that it is on-line. The V-Switch also begins
listening for the keep alive signal from its neighbor. The keep alive signal is
transmitted through all connecting paths between each neighbor. Thus, if one
path fails, the remaining path(s) will still carry the keep alive signal.

If a specified time period passes without a keep alive signal from the neighbor,
a suspicious interval, measured in seconds, is entered. The V-Switch suspects
that its neighbor has gone off-line and begins preparing to activate the neighbor
IP addresses to take over volume exposure.

If a keep alive signal is received during the suspicious interval, the timer is reset
and the V-Switch continues to function as usual. If a keep alive signal is not
received by the end of the suspicious interval, a dead interval is entered. At the
end of the dead interval, the neighboring V-Switch is considered off-line, the
failover process is initiated and the on-line V-Switch actives the neighbor IP
addresses and takes over volume exposure.

5-8 SANRAD V-Switch CLI User Manual

Use the CLI command cluster show to view the keep alive parameters of a
cluster.

cluster show

Last Keep Alive KeepAlive Int(s) Susp Int(s) Dead Int(s)

Example:

Every 2 seconds V-Switch 1 sends out a keep alive signal. If, after 6 seconds
from the last keep alive signal, V-Switch 1 does not receive another keep alive
signal from its neighbor, it enters a suspicious interval. If, after 10 seconds from
the last keep alive signal, V-Switch 1 enters a dead interval and begins
activating the failover process.

Enabling and Disabling Failover

Once you have configured your cluster parameters, you need to enable the
failover functionality. Use the CLI command cluster failover enable to
enable this functionality. This command must be executed on both V-Switches
in the cluster.

cluster failover enable

If you want to break a cluster or need to take a V-Switch off-line, you must first
disable V-Switch failover. Use the CLI command cluster failover
disable to disable this functionality. This command must be executed on
both V-Switches in the cluster.

cluster failover disable

Further V-Switch Cluster Configurations

After configuring neighbor parameters on each V-Switch, you need to configure
identical volume configuration and exposure details on each V-Switch in the
cluster. Please refer to Chapter 6 “Volume Configuration” for information on
configuring volumes. Please refer to Chapter 7 “Volume Exposure &

Security” for information on exposing volumes.

Please refer to Appendix A “Configuring a Cluster” for a working example of a

 A general description and generic diagram.
 The basic command, switches and parameters needed to execute the

command.

 An example of how to use the command with an accompanying

The specific examples used in this chapter contain two JBODs; each JBOD
having four disks, each with a volume of 18 GB. See the example in Figure 6-1.

The Volume Manager names all disks automatically during the auto-discovery
process. For FC, this name includes FC disk’s World Wide Unique Identifier
(WWUI) serial number. For SCSI, this name includes the SCSI disk port number
and SCSI bus ID. This name is important in identifying disks for re-creating
volume hierarchies on both V-Switches in a cluster.

Identifying Available Storage Devices

The V-Switch

supports a maximum

of 512 disks.

Before beginning to configure virtual volumes, you need to know which
storage devices are available. Use the CLI command storage show to
show the available storage devices and their corresponding aliases needed
to configure volumes

The storage device operating status has four options.

 Enabled denotes an attached and functioning storage device.
 Storage is missing denotes that a storage device was previously

registered and has since lost its connection to the V-Switch.

 Invalid denotes a storage device that was connected, removed and

reconnected with a different storage size.

 Unknown denotes that a storage device is connected but is issuing

parameters not understandable to the V-Switch.

If a subdisk has been created on a disk, the subdisk status in the disk details
will display split. If no subdisks were created, the subdisk status will display
entire.

Creating a Transparent Volume

Transparent volumes

cannot be used in

further volume

hierarchies.

You can take a physical disk and its existing configured storage data and
convert it to a directly accessible, or transparent, virtual volume using the
CLI command volume create transparent. A transparent volume is
ready for direct host exposure. Please refer to Chapter 7 “Volume

Exposure & Security”.

Tape devices must

be virtualized as

transparent volumes.

Certain vendor storage devices have vendor-specific SCSI commands. To
support these SCSI commands, you can convert these storage devices and
their contained data to transparent volumes.

This is useful if you have a functioning and fully configured RAID module
that you want to use ’as is’. All RAID configurations will be maintained in
the transparent volume.

You need to define two parameters to create a transparent volume:

6-6 SANRAD V-Switch CLI User Manual

Example:

If you are working in

a V-Switch cluster,

this volume must be

configured on both

V-Switches.

In Figure 6-2, the logical unit, LUN0 on Disk 1, is converted directly to a
virtual transparent volume, Transparent 1. This RAID device has only one
LUN. For each LUN configured on a RAID device, the V-Switch registers
a disk. Therefore, a RAID device with five LUNs will appear to the V­Switch as five disks.

After creating the transparent volume, you can use the CLI command volume
show to verify the volume creation.

Creating a Subdisk (LUN Carving)

You can create one or more subdisks on a physical disk. The subdisks can
then be converted to simple volumes to be used for creating concatenated,
striped and mirrored virtual volumes. When you create a subdisk, only
the defined area is converted into a subdisk. You must individually
convert each disk area into a subdisk for the physical volume to be usable
by the Volume Manager.
