It is recommended to take the information for the root and resume parameters from the
previous line by default.
4. Reboot the server and when the grub menu appears select the SUSE Linux
(2.6.27.19-5-default) with MPP support option as shown in Figure 20-11. It is possible
to make this selection as default by changing the default parameter in the menu.lst file.

20.1.3 Setting up the DS3500 logical drives and host mapping

Map the logical drive(s) to the SuSE operating system by using the normal procedure as
described in Chapter 11, "Administration - Mappings Tab" on page 281.
One of the important things to consider, is using the correct Host type when mapping the
logical drive to the host from the IBM Storage Manager as shown in Figure 20-12.
Figure 20-12 Defining the Host Type of the host
When you define the host port, the host type of the attached host is defined as well. Through
this information, the DS Storage System modifies the NVSRAM settings to behave according
to the host type defined.
The most common of the specifications that differ according to the host type setting is the
Auto Volume Transfer function (AVT), which is set as enable for certain host types, and
disable for others. It is important to carefully choose the correct host type from the list of
