Introduction
Figure 1-1. Global Array Manager Client
Overview
Global Array Manager Client software v2.21 (GAM Client 2.21) is used in
order to:
• Monitor, manage, maintain, and configure Mylex Disk Array
Controllers and the physical and logical drives that are connected to
these controllers, even across remote servers
• Monitor and manage SCSI Host Bus Adapters and the physical devices
that are connected to these adapters, even across remote servers
Manual No. 771961 1-1
Overview
Workstation Array Manager functions very similarly to Global Array
Manager Client, except for the following:
• Workstation Array Manager (WSAM) is used to monitor, manage,
maintain, and configure only Mylex Disk Array Controllers, physical
devices, and logical drives that reside on the individual workstation
where WSAM is running.
• WSAM cannot access remote servers and work with controllers or
devices connected to those servers.
• WSAM runs only under Windows NT, while GAM Client can run
under Windows NT, Windows 95, or Windows 98.
• Workstation Array Manager has no Global Status View and does not
include any of the network-related components available through
Global Array Manager Client.
Most functions of GAM Client 2.21, however, are available in WSAM, so
this manual applies to both versions.
Global Array Manager Components
Global Array Manager has three components:
• Global Array Manager Server component (which is part of the Mylex
Disk Array Controller Software Kit)
• Global Array Manager Client component
• Workstation Array Manager component
Each component handles specific tasks based upon the selected function.
Configuration Functions
Configuration functions are easily performed using RAID AssistTM, an
intuitive, wizard-like utility in the GAM Client and WSAM components that
simplifies the process of setting up or reconfiguring a disk array. Just answer
a few brief questions, and RAID Assist automatically does the rest. Use
Manual Configuration for more control over drive group setup or individual
configuration parameters.
1-2 GAM Client v2.21 and WSAM User’s Manual
Introduction
Monitoring Functions
The Global Array Manager Server component collects and disseminates
information on disk array or HBA subsystem status and resource utilization.
The Global Array Manager Client component organizes this information
through an intuitive graphical display. Errors and events are recorded in a
log, and if a problem is serious enough to warrant immediate attention,
operators can be alerted via popup windows, pagers, fax, or email if so
desired.
Maintenance Functions
The Global Array Manager Client or Workstation Array Manager manages
or performs maintenance on individual disk arrays and drives (with the
appropriate authentication), again by means of the graphical user interface.
This includes removing physical devices from operation in a functioning
disk array (also known as “killing” or off-lining a drive), rebuilding drives,
selecting hot spares, and initiating a check of consistency (or parity)
information on arrays that are configured to support redundancy. The Global
Array Manager Server executes the management instructions specified by
the Global Array Manager Client.
What’s New In GAM Ver sion 2.21?
Global Array Manager Version 2.21 contains new features, enhancements,
and modifications not available in earlier versions of Global Array Manager:
Support for the Mylex DAC960FF External RAID Controller. In
addition to support for earlier External SCSI RAID Controllers such as the
DAC960SX, and External Fibre Channel RAID Controllers such as the
DA C960SF and D AC960FL, GAM V ersion 2.21 adds full support (including
controller options) for the DAC960FF Fibre Channel-to-Fibre Channel
RAID Controller.
Support for Disk Array Controllers Using PCI Firmware 4.07. Version
2.21 of GAM supports Mylex PCI-Based Disk Array Controllers which run
Mylex PCI Firmware up to and including Version 4.07.
Support for Disk Array Controllers Using PCI Firmware 5.07. Version
2.21 of GAM supports Mylex PCI-Based Disk Array Controllers which run
Mylex PCI Firmware Version 5.07.
Manual No. 771961 1-3
What’s New In GAM Version 2.21?
Remote Firmware Upgrade for External RAID Controllers. Version
2.21 of GAM includes a Flash Utility to allow an easy method of upgrading
the firmware on your Mylex External SCSI and Fibre Disk Array Controllers
when enhanced firmware releases become available.
New Workstation Array Manager (WSAM) Component. Shipped with
Global Array Manager 2.21 is a Workstation Array Manager component
which runs on Windows NT workstations. This component is an alternative
to Global Array Manager Server and Client when a user only needs to
monitor, manage, maintain, and configure controllers, physical devices,
logical drives, and disk arrays that are directly connected to the workstation
running WSAM. For remote server access, GAM Server and GAM Client
must be used instead.
Simplified Global Array Manager Component and Subcomponent
Installation under Windows NT/95/98. Version 2.21 of GAM includes an
enhanced installation wizard which simplifies and combines installation of
all GAM components and subcomponents from the distribution CD-ROM
when running under Windows NT/95/98. Under Windows NT, the user can
choose to install GAM Server, GAM Client, or WSAM, WSAM by itself, or
both GAM Server and GAM Client together. In addition, subcomponents of
GAM Server such as DMI and SNMP can be individually selected or
deselected for installation.
Basic Support for PCI Clustering. Version 2.21 of GAM includes support
for basic PCI clustering through Controller Options, with optional Host ID
change.
Support for External Controller Battery Backup Units (BBUs). Version
2.21 of GAM adds support for Mylex External RAID Controller BBUs.
Enclosure Management for External Fibre Controllers. Version 2.21 of
GAM adds SES Enclosure Management support for Mylex External Fibre
Channel Controllers such as the DAC960FF. The Enclosure option can be
selected from the Administration menu or from within the Controller View
of a Fibre Channel controller.
Other Functional and User Interface Enhancements. Numerous
enhancements have been made to GAM, including the following: enhanced
controller options and parameters for PCI and External controllers, a new
controller information layout for External Controllers, and the ability to
disable logical drive background initialization.

Configuration
Introduction
Configuration activities involve the following:
• Setting up server groups and servers (GAM Client only)
• Loading a configuration from disk and saving it to the controller
• Setting or modifying user preferences such as alarms, alerts, event
message editing, and communications parameters
• Setting or modifying controller options to suit your application needs
• Creating, modifying, or deleting Mylex RAID Controller
configurations
• Mapping LUNs (External RAID operation only)
Signing On to a Server
Security Access Levels
The ability to perform certain actions within the Global Array Manager
Client depends on your security access level.
There are three levels of security access, Guest (no sign-on), User, and
Administrator.
Guest
By attaching to a file server through the Global Array Manager Client, a user
is automatically assigned Guest (no sign-on) status. Guest users can monitor
Global status and the Log Information V ie wer. They cannot make changes to
any parameters or configurations.
User
A User has ordinary system privileges. A User signs on with his or her
username and a password that has been assigned by the Administrator of that
server. A User can alter parameters of anything that is not controller or drive
related, and also monitor the status of any selected controller and RAID
Manual No. 771961 4-1
Signing On to a Server
subsystem, but has no administrative capability. The User cannot set up or
modify configurations, kill drives, rebuild drives, or change their on-line
status. In essence, Users can “look”, but they can’t “touch.”
Administrator
Individuals with Administrator security access have the capabilities of
Guests and Users plus the ability to manipulate controllers and RAID
subsystems. These additional abilities include configuration, drive kill, drive
rebuild, and drive state changes. An Administrator initially signs on as
“gamroot” and secures his or her access with a password.
Under Windows NT, the Global Array Manager uses security features built
into Windows NT.
Signing On
To gain access capabilities beyond Guest level, you must sign on to a server.
If you double-click a server from the Global Status View window when you
are not already signed on, then click on any option that requires
Administrator rights, the Sign On dialog box appears automatically (Figure
4-1).
Figure 4-1. Sign On Dialog Box

Configuration
Open Sign On at any time as shown in Figure 4-2:
Figure 4-2. Select “Sign On”
Do the following:
1. Type the password previously enabled on the server that corresponds
with username “gamroot.”
This should provide Administrator access privileges.
2. Check the box labeled “Remember password for this session” if you
want GAM to refrain from Sign On messages each time you select a
server during this session which uses the same password. This amounts
to automatic sign-on on additional servers and should be used with
caution.
Uncheck the box if you want to retain the option of signing on to each
server you wish to access individually.

In the Controller Options dialog box (Figure 4-22), you have the option to do
any of the following:
• Enable (by checking) or disable (by unchecking) any of the following
Global Parameters:
• Automatic Rebuild Management. Works in conjunction with SAF-
TE disk array enclosures to detect removal of a failed drive and
perform an automatic rebuild after installation of a replacement
drive.
• Active Negation. Recommended for cleaner SCSI signal transitions.
• Read Ahead. Reads data to the next stripe boundary (based on stripe
size) and retains in cache any data beyond the size of the actual read
request.
• Disconnect On First Command. Allows target to disconnect from
initiator.
• Background Initialization. Allows logical drive initialization to
take place “behind the scenes” so that the logical drive is
immediately available for use. If you disable this option, logical
drives will need to complete their initialization process before they
can be used.
• Change the default Rebuild Rate to less than or equal to 50.
A rate of 50 devotes the maximum allowable resources to a drive
rebuild or array expansion, allowing the Rebuild or Expand to proceed
at its fastest. Lowering the number devotes more resources to I/Os and
consequently slows the Rebuild or Expand Array process.
• Change any of the following Startup Parameters:
• Spin-up. Change if you do not want automatic drive spin-up.
• Devices Between Spins. Number of devices to spin up at one time.
A low number lessens the likelihood of a power drain.
• Initial Delay . Number of seconds between ph ysical device start-ups.

spin-up cycles.
• Change any of the following SCSI Parameters (note that Transfer
Speed is read only):

(LVD only).
• SCSI Tag Queuing. Enable in order to queue up commands to be
executed by the target.
• Enable (by checking) or disable (by unchecking) the following
Clustering Parameter:
• Clustering. Under Windows NT 4.0, allows redundancy among
controllers in various servers. If a controller or server fails, another
controller can take over the disk drives and disk arrays that were
formerly handled by the failed controller. This mechanism imparts a
“fault tolerance” among controllers and servers.
• Change the following Clustering Parameter:
• Controller Host ID. Change if you want to set this controller’s
target ID to something other than 7.

In its simplest form, RAID Assist provides an Auto Configuration option
which immediately configures all available drives into an optimal, RAID 5
configuration. RAID Assist’s Assisted Configuration sets up a new array
according to predefined parameters, and asks the user questions to gather the
key information necessary to build the array.
If configuration needs go beyond what Auto or Assisted Configuration

Back caching. This improves performance but puts data at risk. You
should have a battery backup unit or uninterruptable power supply if
selecting this feature.

Configuration
4. Check the Init Drive box if you want this logical drive to be fully
initialized at the conclusion of the configuration. It is recommended
that you check this option (if available), unless the controller is capable
of background initialization. If so and you check the box, you’ll see a
message when you apply the configuration indicating that you can
make use of the background initialization support.
5. If this is your first logical drive, select a stripe size. This setting will
apply to all logical drives on this controller.
6. If this is your first logical drive, select a cache line size. Available
settings will depend on the selected stripe size. (Not available for
External RAID Controllers.)
7. Click the Add Drive button to register your new logical drive.
8. If you are configuring a Mylex PCI RAID Controller, click Apply to
save the configuration if you are finished setting up logical drives, OR
Repeat the process above to set up additional logical drives, then click
Apply when you’re done.
If you are configuring a Mylex External RAID Controller, click the
LUN Mapping tab to continue with configuration (see “LUN Mapping
in Global Array Manager” on page 4-52), OR
Repeat the process above to set up additional logical drives, then click
the LUN Mapping tab when you’re done.
An example of a completed Manual configuration is shown in Figure 4-45:

Note
In Manual Configuration, Add Logical Drive and
Expand Array function very similarly to what was
shown above. In each of these two cases, however,
RAID Assist shows you the disk arrays and logical
drives and allows you to add to the configuration
without risking existing data.

External RAID Controller Operation Overview
External RAID Controllers use their host ports to connect to one or more
Host Bus Adapters in one or more host computer systems.
Depending on the model and configuration of the controller, there may be
from one to four host ports. Each configured logical drive consumes a
particular bus-target ID-LUN on the host system. Multiple sets of disk dri ves
are connected to the controller via its drive channels. There may be as many
as six drive channels, depending on the controller model and configuration.
In duplex, or Active/Active mode, two identical External RAID Controllers
are connected to the same hosts via their host ports, to the same drives via
their drive channels, and to each other via a special hardware link for
heartbeat sensing. This forms a redundant controller system. The two
controllers work together handling data traffic and mirror their write data in
each other’s cache memory. If one of the controllers fails or otherwise
becomes non-operational, the surviving controller takes over its
responsibilities with no loss of data.
☛Note
This section presents only a brief introduction to
External RAID Controller operation. For additional
details, consult the hardware installation guide for the
particular controller of interest.
LUN Mapping Overview
External RAID Controller LUN Mapping allows logical drives (or system
drives) to be made available or unavailable on one or more host ports. The
mapping is performed by assigning Logical Unit Numbers (LUNs) to logical
drives. The LUN assignments are per host port and are independent of the
assignments on other host ports. Logical drives may be assigned only one
LUN per host port.
By not assigning a LUN to a logical drive on a particular host port, that
logical drive is made inaccessible to that host port.
Manual No. 771961 4-51
External RAID Controller Operation Overview
LUN Mapping in Global Array Manager
Global Array Manager implements LUN Mapping by allowing the user to
map Logical Unit Numbers (LUNs) to specific controller/port combinations.
After configuring the desired number of logical driv es on the Mylex External
RAID Controller, click the LUN Mapping tab in Manual Configuration
(Figure 4-46). (The Controller-Port columns are shown or not shown
depending on the current controller configuration of host ports and duplex
controllers.) By default these logical drives are made a vailable to all existing
host ports in the configuration. LUNs are assigned automatically in
sequential order for each port.

,
WARNING
If Global Array Manager Server is running under
Windows NT, be sure to assign each logical drive to
a specific, individual port (not to all ports). When
logical drives are available to ALL host ports,
Windows NT may assign multiple volumes (e.g. C:
and E:) to the same physical media. Data
corruption and/or data loss can result.
