DS400 and has the name A0 in the CLI for controller A and B0 for controller
B.
Second Host bus adapter (HBA2), an IBM SMB Host Bus Adapter, is installed
in slot 4 and is detected by IBM FAStT MSJ as port 1. The world wide name
has got the alias RIOGRANDE-S4-(1) assigned. This HBA has access to FC1
from controller A and B. Port FC1 as described on the rear site of the
TotalStorage DS400 and has the name A1 in the CLI for controller A and B1
for controller B.
The logical drive used to boot from is named RIOGRANDE-BOOT.
Each switch has a zone for each connected HBA configured. Soft zoning was
used. Every world wide name has got an alias. The alias was used during zone
configuration. SAN switch 1 has got configured a zone Z_RIOGRANDE_HBA1 with
the members A_RIOGRANDE_HBA1, A_DS400_1_A_FC0 and A_DS400_1_B_FC0. SAN
switch 2 has got configured a zone Z_RIOGRANDE_HBA2 with the members
A_RIOGRANDE_HBA2, A_DS400_1_A_FC1 and A_DS400_1_B_FC1. The zones where
added to a configuration and the configuration was activated.
Note: It is important for this description that the array of the logical drive
RIOGRANDE-BOOT is owned by controller A. When the alternate controller owns
the array of the logical drive, the port names needs to be changed to reflect
that the access goes over a port of controller B and not A.
9.1.3 TotalStorage DS400 setup
For the installation, only one logical drive was created. The world wide names
where manually added into the initiator configuration and this logical drive was
added to both initiators. At time this redbook was written, no multipathing driver
was available. This driver can be installed after the operating system installation.
To prevent trouble with multiple disk drives with the same signatures, the allowed
ports for an initiator to access a logical drive where modified. The result is that
only a single logical drive is seen during installation time and no recabling or
change in the zoning configuration is required. By default, an initiator is allowed
to access a logical drive over all for fibre channel ports. The CLI supports
disabling and enabling every port for a given initiator. To get more details on
managing a TotalStorage DS400 see Chapter 4, "TotalStorage DS300 and
DS400 management" on page 67. 4.8.2, "Create arrays, logical drives, and
access control on the TotalStorage DS400" on page 131 explains in detail the
creation of logical drives and array. The steps below explain the tasks performed
after the array and logical drive creation.
