Connecting Ssa Disk Drives - IBM Advanced SerialRAID/X Installation Manual

Attention:
The Windows NT 4.0 SSA Device Driver supports up to 6 IBM Advanced SerialRAID/X
Adapters in one machine; the Netware SSA Driver supports up to 4 IBM Advanced
SerialRAID/X Adapters. Other restrictions may apply to individual machines.
If you are using a Netfinity Model 5500 or 5500M10, you can have up to two IBM
Advanced SerialRAID/X Adapters on the primary bus. However, you cannot place both
an IBM SerialRAID Adapter and an IBM Advanced SerialRAID/X Adapter on the primary
bus of the Model 5500 or 5500M10.
Netfinity Model 5500M20 cannot use slots 5 or 6 for the IBM Advanced SerialRAID/X
Adapter due to size restrictions..
If you are using a Netfinity Model 7000, do not install the adapter in slot 5 if you are
using more than one Advanced SerialRAID/X Adapter. If you use slot 1 or slot 6 for
SSA Adapters then any other high performance adapters should be placed on the other
PCI bus.

Connecting SSA Disk Drives

After you install the IBM Advanced SerialRAID/X Adapter and reinstall the cover of your
system unit, you can connect the SSA disk drives.
To connect the disk drives:
1. Refer to the configuration plan that was created at the time that your SSA
subsystem was ordered. If this plan is not available to you, use the sample
configuration information that is provided in the documentation for the unit in which
the SSA disk drives are installed. ("Appendix A. Connecting SSA Devices to the
Adapter" on page 31 provides some general information on SSA configurations.)
2. Using this information connect the SSA cables to the unit in which the disk drives
are installed.
Note: If you are adding SSA disk drives under the covers of your system unit, refer
3. Connect the SSA cables to the IBM Advanced SerialRAID/X Adapter.
4. If not already connected, connect power to the unit in which the SSA disk drives are
installed and to your system unit. The installation instructions for each unit describe
how to do this.
