IBM System Storage Subsystem DS5020 - Manual (Page 41)

Setting up IP addresses for DS5020 storage controllers
After you install DS Storage Manager (as described in the DS Storage Manager
Installation and Support Guide for your host operating system), complete one of the
following procedures to set up IP addresses:
v “Steps for setting up the DHCP/BOOTP server and network”
v “Steps for assigning static TCP/IP addresses to the DS5020 controllers”
Steps for setting up the DHCP/BOOTP server and network: To complete this
procedure, you must have the following components:
v A DHCP or BOOTP server
v A network management station (NMS) for Simple Network Management Protocol
(SNMP) traps
v A host that is connected to a storage subsystem through a Fibre Channel I/O
path
v A management station that is connected by an Ethernet cable to the storage
subsystem controllers
Note: You can avoid DHCP/BOOTP server and network tasks either by using the
default controller IP addresses, or by assigning static IP addresses to the
controller, as described in the next section.
Complete the following steps to set up the DHCP/BOOTP server and network:
1. Get the MAC address from each controller blade.
2. Complete whichever of the following steps is applicable for your server:
v On a DHCP server, create a DHCP record for each of the MAC addresses.
Set the lease duration to the longest time possible.
v On a BOOTP server, edit the bootptab file to add in the entries that associate
the MAC address tab with the TCP/IP address.
3. Connect the DS5020 storage subsystem Ethernet ports to the network.
4. Turn on the DS5020 storage subsystem.
The DHCP server automatically assigns new IP addresses to the controller Ethernet
port.
Steps for assigning static TCP/IP addresses to the DS5020 controllers: To
complete this procedure, you must have the following components:
v A host that is connected to a storage subsystem through a Fibre Channel I/O
path
v A management station that is connected by an Ethernet cable to the storage
subsystem controllers
For a host that is connected to a storage subsystem through a Fibre Channel I/O
path: Complete the following steps to assign static TCP/IP addresses to the
DS5020 storage subsystem controllers by way of the host that has Fibre Channel
connectivity to the DS5020 Fibre Channel host port.
Note: You cannot perform in-band management with a host that has iSCSI
connections to the DS5020 until it is configured. Use an out-of-band
management connection instead.
1. Install the DS Storage Manager client software in the host, and make sure that
the SMagent software is installed and running.
