Configure The Disk Space In Windows Server 2008 - IBM System Storage DS3500 Introduction And Implementation Manual

SAS configuration guide for Windows on IBM BladeCenter.fm
We will install DS Storage Manager 10 Utilities, because this will allow us to run the
utility and hence avoid the necessity to reboot the host server when adding new logical drives.
Since the host server contains a 2-port SAS Expansion Card, we require multipath support.
This is installed as part of the Host selection when installing the DS Storage Manager.
For the exact installation steps, see Chapter 5, "Installing IBM System Storage DS Storage
Manager" on page 133.
Once the DS3500 Storage Manager client is installed, we have to add the DS3500 subsystem
in the Enterprise Management window and prepare the logical drives for our Windows server.
For simplicity's sake, we create just one logical drive of 20 GB.
We also have to define our Windows Server 2008 host in the Storage Manager and map it to
the logical drive.
We have already explained how to add storage subsystems, define hosts, prepare logical
drives, and map them in Chapter 11, "Administration - Mappings Tab" on page 281, so we do
not repeat these steps here. Figure 18-15 shows our 20 GB logical drive named Data and
mapped to the host server Blade04.

18.4 Configure the disk space in Windows Server 2008

The logical drive now must be recognized in Windows before we can start using the disk
space. One possibility is to shut down and reboot the host server or to select Rescan Disks
from Action menu bar of Disk Management window. But there is a better alternative; We use
the hot_add utility (a part of SMutil).
By default, the hot_add executable is located in C:\Program Files (x86)\IBM_DS\util. In a
command prompt window, change to this directory. If you installed the DS3500 Storage
Manager in a non-default directory, change to that directory instead, and then to subdirectory
util. Now run hot_add.
