162 EMC Ionix ControlCenter 6.1: Taking Control of Your Datacenter
Configuring and Controlling Your Datacenter
Discovering host devices
The administrator has completed storage allocation and now updates the disk
information on the host after the configuration change.
To do this, the administrator:
1. In the Console tree, right-clicks host l82ar136 and selects Host, Rescan Disks.
Note: Host agent must be installed in order to see the Hosts, Rescan Disks option.
A login dialog box appears the first time during the session that an attempt is
made to perform a command that requires user authentication on this host.
2. Enters the Username and Password that provide the necessary privileges to
complete the rescan task on this host.
3. Once the rescan completes, right-clicks host l82ar136 and selects Rediscover.
The Discover data collection policy runs, and the host information in the Console
is updated.
Figure 144 on page 163 shows the new LUNs appearing in the Storage Group for
l82ar136 in the Console tree. The server sees the devices after rediscovery is
complete. The administrator has completed the allocation of LUNs to the
application server.
