Note: When using two cards in a server, configure the cards to access
different logical drives to do a load sharing. Currently the driver does not
support multipathing to a logical drive using multiple HBAs. We tested device
mapper and the multipath-tools for multipathing, but experienced problems as
the readsector0 checker reported failed paths online again after some

7.4 IBM iSCSI Server Adapter in Windows Server 2003

7.4.1 Planning, considerations and network setup

Two IBM iSCSI Server adapter are installed in an IBM ^xSeries 445 in
slot 5 and 6. As operating system a Microsoft Windows Server 2003 Enterprise
Edition with service pack 1 was chosen. Even with two iSCSI server adapters no
redundant paths are usable because there is right now no multipath driver for the
TotalStorage DS300 available. In case of an HBA failure all logical drives
assigned to the failed initiator can be manually migrated to the other initiator. In
worst case a reboot might be required. All drives should come up with the same
