Configuration Of The Ibm Iscsi Server Adapter Card - IBM TotalStorage DS300 Best Practices Manual

7.4.5 Configuration of the IBM iSCSI Server Adapter Card

The IBM iSCSI Server Adapter Card can be configured in its BIOS during system
POST (by pressing CTRL+Q) or with the iSCSI SANsurfer Management
Software.
The configuration is almost the same as described in 7.2.3, "Setup of the QLogic
iSCSI Expansion Card for IBM eServer BladeCenter" on page 291. The only
difference is that the IBM iSCSI Server Adapter Card is a single port card.
Therefore, a single port is displayed in the SANsurfer iSCSI HBA manager
application for each installed HBA.
Note: When using two cards in a server, configure the cards to access
different logical drives to do load sharing. Currently, the driver does not
support multipathing to a logical drive using multiple HBAs.
The final configuration looks as shown in figure Figure 7-145 on page 319. HBA
0 accesses the logical drives DANUBE-DISK1 and DANUBE-LOG over the IP address
192.168.1.61. This is ETH2 of controller A. Those two logical drives are in the
same array which is owned by controller A. Only HBA 0 has access to those
logical drives.
HBA1 has access to the logical drives DANUBE-MAIL and DANUBE-DB over
192.168.1.126. This is the IP address of ETH3 of controller B. Both logical drives
are in their own array. Both arrays are owned by controller B.
Logical drive DANUBE-PRINT is also accessed by HBA1. The array this logical drive
is in is owned by controller A. HBA1 gets access over the IP address
192.168.1.125. This is the IP of ETH3 of controller A.
Note: Please remember to configure the ARP redirect and Keep alive timeout
as described in 7.1.10, "Configure iSCSI host bus adapter firmware settings"
on page 261.
