About Your Host
Configuring Host Access
Dell PowerVault Modular Disk Storage Manager (MD Storage Manager) is comprised of multiple modules. One of these
modules is the Host Context Agent, which is installed as part of the MD Storage Manager installation and runs
continuously in the background.
If the Host Context Agent is running on a host, that host and the host ports connected from it to the storage array are
automatically detected by the MD Storage Manager. The host ports are displayed in the Host Mappings tab in the Array
Management Window (AMW). The host must be manually added under the Default Host Group in the Host Mappings
tab.
NOTE: On MD3260i and MD3660i storage arrays that use the iSCSI protocol, the Host Context Agent is not dynamic
and must be restarted after establishing iSCSI sessions to automatically detect them.
Use the Define Host Wizard to define the hosts that access the virtual disks in the storage array. Defining a host is one of
the steps required to let the storage array know which hosts are attached to it and to allow access to the virtual disks.
For more information on defining the hosts, see
Defining A Host .
To enable the host to write to the storage array, you must map the host to the virtual disk. This mapping grants a host or
a host group access to a particular virtual disk or to a number of virtual disks in a storage array. You can define the
mappings on the Host Mappings tab in the AMW.
On the Summary tab in the AMW, the Host Mappings area indicates how many hosts are configured to access the
storage array. Click Configured Hosts in the Host Mappings area to see the names of the hosts.
A collection of elements, such as default host groups, hosts, and host ports, are displayed as nodes in the object tree on
the left pane of the Host Mappings tab.
The host topology is reconfigurable. You can perform the following tasks:
• Create a host and assign an alias or user label.
• Add or associate a new host port identifier to a particular host.
• Change the host port identifier alias or user label.
• Move or associate a host port identifier to a different host.
• Replace a host port identifier with a new host port identifier.
• Manually activate an inactive host port so that the port can gain access to host specific or host group specific
LUN mappings.
• Set the host port type to another type.
• Move a host from one host group to another host group.
• Remove a host group, a host, or a host port identifier.
• Rename a host group, or a host.
Using The Host Mappings Tab
In the Host Mappings tab, you can:
• Define hosts and hosts groups
