5 Storage Allocation
Allocating group storage space to users involves the following steps:
1. Create a Volume on page 23 .
2. Connect a Computer to a Volume on page 27 .
After allocating storage, you can customize the group and use its more advanced features. See
Where to Go After Setting Up a Group on page 29 .
Create a Volume
To allocate group storage space to users and applications, use the Group Manager CLI or GUI
to create volumes. A volume appears on the network as an iSCSI target. When you create a
volume, specify the information described in
Table 8 .
Table 8: Volume Configuration Information
Component Description
Volume name
A unique name, 63 or fewer characters (including letters, numbers, periods,
hyphens, and colons). The volume name is appended to the end of the iSCSI target
name, which is automatically generated for the volume. Access to a volume is
always through the target name.
Volume size
The reported size of the volume as seen by iSCSI initiators. The minimum volume
size is 15MB. Volume sizes are rounded up to the next multiple of 15MB.
Optionally, you can set aside space for volume snapshots or configure a volume with thin
provisioning. However, thin provisioning is not appropriate for all storage environments. See the
Dell EqualLogic Group Manager Administrator's Guide for information about advanced volume
functionality.
Using the CLI to Create a Volume
1. Log in to the group.
Use one of these methods to connect to the group:
• Serial connection to a member. See Set Up a Serial Connection to the Array on page 13 .
• Telnet or ssh connection to the group IP address.
At the login prompt, enter the
grpadmin
account name and the password that you specified
when creating the group.
2. At the Group Manager command prompt, use the following command to create the volume:
volume create volume_name size [GB]
Specify the volume name and size (the default unit of measure is megabytes).
3. Use the following command to create an access control record for the volume:
volume select volume_name access create access_control
The
access_control
parameter can be one or both of the following options:
•
initiator initiator_name
