Allocating storage to a host from a Symmetrix array 119
Configuring and Controlling Your Datacenter
Implementing changes
Using SAN Advisor’s Compare Report as a guide to install, connect, and configure the
new host and storage requirement, the administrator should verify that:
◆ The host contains all required software, HBAs, and drivers.
◆ The host can connect to the storage array where its storage requirement resides.
◆ The storage requirement is protected by the appropriate RAID level.
◆ The storage requirement has the required local and remote replicas.
Verifying correct plan information
To verify that the changes are correct, the administrator:
1. Takes a second snapshot of the Ionix ControlCenter environment where the host
was added, as described in “Validating an existing SAN environment” on
page 102.
2. Checks the appropriate snapshots for comparison, and clicks Compare, as
described in “Building an action plan” on page 117.
3. Compares the snapshot to the design containing the recently modeled changes. If
the new host was implemented correctly, the Compare Report will not contain any
differences (Figure 100).

Allocating storage to a host from a Symmetrix array
This example demonstrates adding additional storage from a Symmetrix array to a
new Sun Solaris database host (l82ar156) that has been added to the datacenter.
