The Create New Cluster wizard in the SAN Volume Controller Console provides
setup for creating a new cluster.
Introduction
Use the Create New Cluster–Introduction
panel to learn about the actions that are performed with the wizard.
The wizard guides you through all the actions that are necessary to
create a cluster for the first time. Before you complete the wizard,
install the site certificate served by the cluster on your Web browser.
The wizard asks you to complete the following actions:
- Specify a name of the cluster
- Create cluster superuser and service user passwords
- Specify the cluster IP address for service access
- Specify the fabric speed for the cluster
- Provide license information
Actions
The following action is available:
- Continue
- Click this button to move to the next panel in the Create New
Cluster wizard. The next panel will ask you to specify properties
for the cluster such as cluster name, fabric speed, and IP address.
Enter cluster settings
Use
this panel in the Create New Cluster wizard to specify cluster properties
such as cluster name, fabric speed, and IP address.
Fields
You
can update the following fields:
- Cluster Name
- Enter a name of the cluster. A valid cluster name
is 1 to 15 ASCII characters. The following characters can be used:
a - z, A - Z, 0 - 9, -, or _. The cluster name cannot begin with a
number or the dash (-) character. You must choose a name that
is different from any other cluster name in your storage area network,
even remotely attached clusters. The
cluster name forms part of the iSCSI Qualified Name (IQN) that might
be used when connecting hosts to SAN Volume Controller using
iSCSI. The cluster name should be created and finalized before configuring
any iSCSI hosts.
- Cluster
Superuser Password
- Enter the cluster superuser password that you want to
use to access all cluster maintenance functions. This password must
be different from the temporary cluster superuser password that was initially
provided on the front panel of the node. The temporary cluster
superuser password is used to create the cluster and to initially
sign on to the cluster. Passwords must meet the following requirements:
- Passwords are a maximum of 6 to 64 printable ASCII characters.
- Passwords are case-sensitive.
- The first or last character cannot be a blank character.
Re-enter the password to verify the password.
- Allow cluster superuser password to be reset
from the front panel
- Select this option if you want the ability
to reset the cluster superuser password from the front panel. This
option allows you to reset the cluster superuser password from the
front panel in the event the password is forgotten. Enabling this
policy allows you access in case the cluster superuser password is
forgotten. If you leave this policy enabled, you must ensure adequate
physical security to the cluster hardware. If you select this feature,
you must ensure adequate physical security to the cluster hardware.
You can view or change the status of this feature at any time after
the cluster has been created.
- Service Password
- Enter the service password, which is used for routine
cluster service activities. The service password allows the service
user to access a limited subset of the maintenance functions available
to the user that is defined as the superuser. This can be useful if you want
to give different users different levels of maintenance access.
Passwords must meet the following requirements:
- Passwords are a maximum of 15 alphanumeric characters.
- Passwords are case-sensitive.
- Valid characters are uppercase letters (A - Z), lowercase letters
(a - z), digits (0 - 9), dash ( - ), and underscore ( _ ).
- The first character cannot be a dash ( - ).
- Service IP Address
- Enter the service IP address for the cluster. The
system uses the service IP address when a single node is in service
mode. The service mode IP address can be either a fixed IP address
or use Dynamic Host Configuration Protocol (DHCP) IP address. When
using a fixed IP address, you cannot mix IPv4 and IPv6 addresses in
the basic cluster configuration. Therefore, if the cluster IP address,
previously configured on the front panel, is an IPv6 address then
the service IP address must also be an IPv6 address and similarly
for IPv4. When using DHCP, an IP address is dynamically allocated
when the node enters service mode. With DHCP, you can have multiple
nodes in service mode simultaneously. Service mode IP addresses, including
DHCP-assigned addresses, display on the front panel when a node is
in service mode.
- Fabric Speed
- Select the fabric speed. If your cluster contains
nodes that automatically negotiate the fabric speed then this setting
has no effect on those nodes. Node model SAN Volume Controller 2145-8F2
does not automatically negotiate their fabric speed and only operate
at 1 or 2 Gbps; therefore, the fabric speed for these node models
can be set at 1 or 2 Gbps. If your cluster contains nodes that automatically
negotiate the fabric speed, set this value to 2 Gbps, even if the
fibre channel operates at 4 Gbps.
Actions
The following actions are
available:
- Create New Cluster
- Click this button to create the cluster with the settings that
you specified on this panel. After a few seconds, the cluster is created
and the series of status panels are displayed. Click Continue on
each of these panels. The License
Setting panel is displayed.
License settings
Use the License Settings
panel in the Create New Cluster wizard to select the appropriate licensing
scheme for your cluster. The licensing scheme you select is authorized
by the product license that you purchased. If you do not know the
licensing scheme that is authorized by your license, verify your license
information or contact your IBM® sales
representative.
Capacity licensing
is based on the number of terabytes (TB) that are available for base
virtualization, and the FlashCopy® feature
and the Metro Mirror and Global Mirror feature. Capacity licensing
is the initial licensing scheme if you purchased SAN Volume Controller (5639-VC*).
Physical disk licensing is based on the number of
physical disks that you are virtualizing and whether you selected
to license the FlashCopy feature,
the Metro Mirror and Global Mirror feature, or both of these features.
If you purchased SAN Volume Controller Entry
Edition (5639-VW*),
then physical disk licensing is your initial licensing scheme.
When you install SAN Volume Controller,
you must select the appropriate licensing scheme that the purchased
product license authorizes you to use. You can later change from
physical disk licensing to capacity licensing, but you must purchase
the alternative licensing scheme through IBM.
Fields
The following fields are available:
- 5639-VC* Capacity Licensing
- Select this option if you purchased SAN Volume Controller (5639-VC*).
With this type of licensing, you select the number of terabytes that
is available for your license for base virtualization, the FlashCopy feature, and the
Metro Mirror and Global Mirror feature.
- 5639-VW* Capacity
Licensing
- Select this option if you purchased SAN Volume Controller Entry
Edition (5639-VW*).
This licensing scheme is based on the number of physical disks that
you are virtualizing and whether you selected to license FlashCopy feature, the Metro Mirror and
Global Mirror feature, or both of these features.
Actions
The following
action is available:

- Click this button to set license settings for the selected license
scheme.
Capacity licensing settings
Use
the Capacity License Settings panel in the Create New Cluster wizard
to specify license information for your cluster. To remain within
the terms of your license, you must enable only the options specified
in your license.
Use this licensing scheme if you
purchased SAN Volume Controller (5639-VC*).
With this type of licensing, you select the number of terabytes that
are available for your license for virtualization, for Metro Mirror
and Global Mirror relationships, and for FlashCopy mappings. The license applies
to the entire site, so you need to allocate capacity for all the clusters
that are located on the site. The virtualization limit represents
the amount of storage that you are permitted to virtualize for the
cluster. It must be set to a nonzero value before you can use the
system. Verify your license information to determine the following
information: - The amount of virtual storage (in terabytes) that your license
permits
- The Metro Mirror, Global Mirror, and FlashCopy capacities that your license
permits
Fields
You can update the following fields:
- Virtualization Limit (Terabytes)
- Enter the amount of storage that you have allocated
for this cluster. It must be set to a nonzero value.
Note: Only whole
number values are valid for the virtualization limit.
