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. Component Volume name Volume size Table 8: Volume Configuration Information Description 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. 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 14. • 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 • ipaddress ip_address 23

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 14
.
•
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
•
ipaddress
ip_address
