To connect the 5886 disk drive
enclosure to one or more Serial-attached SCSI (SAS) adapters
or to a system with support for a SAS drawer, complete the following
steps.
For additional information related to SAS cabling and
cabling configurations, see Serial-attached SCSI cable planning.
- Confirm that all adapters that you need
to connect to the 5886 disk
drive enclosure have been installed in the system. If the adapters
have not been installed, complete the adapter installation procedure
for your system before continuing with this task.
- If the server requires an internal cable
to be installed to produce an external SAS port for connection with
the 5886 disk
drive enclosure, confirm that the installation has been performed.
Review the following list of systems that require the installation
of an external SAS port, and then complete the action for your system,
if required:
Remember: When installing or confirming the
use of an external SAS port, record the location of the external SAS
port on the server. Later in this procedure, you are instructed to
install the external SAS cable to this server connector location.
- For installing the external SAS port on the IBM® Power® 710 Express (8231-E2B and 8231-E1C) or IBM Power 730 Express (8231-E2B and 8231-E2C), see Installing
the external SAS port in the 8231-E2B, 8231-E1C, 8231-E1D, 8231-E2C,
or 8231-E2D.
- For installing the external SAS port on the IBM Power 720 Express (8202-E4B, 8202-E4C, and 8202-E4D) or IBM Power 740 Express (8205-E6B, 8205-E6C, and 8205-E6D), see Installing
the external SAS port in the 8202-E4B, 8202-E4C, 8202-E4D, 8205-E6B,
8205-E6C, or 8205-E6D system.
- For installing the external SAS port on the IBM Power 750 Express (8233-E8B) or IBM Power 755 (8236-E8C), see Installing
the external SAS port on an 8233-E8B or 8236-E8C.
- For installing the external SAS port on the IBM Power 770 (9117-MMB, 9117-MMC, and 9117-MMD) or IBM Power 780 (9179-MHB, 9179-MHC, and 9179-MHD), see Installing the external SAS port
in the 9117-MMB, 9117-MMC, 9117-MMD, 9179-MHB, 9179-MHC, or 9179-MHD.
- Locate the connection for each adapter for which you
are using an external SAS cable to connect the 5886.Adapter cables attach to ports at the rear of the servers in which
the adapters are installed. To identify the SAS port location for
the server in your configuration, see Server
connectors.
Note: The configuration figures in step
4 use adapter cards to represent
the external server connections. The adapter card can represent one
of the following connection types:
- The external port of an adapter that you confirmed in step 1.
- The external port of an internal adapter cable that you confirmed
in step 2.
- Choose one of the following options to cable the SAS
adapter.
Note: Adapters
are cabled to the
5886 by
using ports at the rear of the enclosure. To learn about the enclosure
ports that are used in the following options, see
Enclosure
connectors.
- To perform a connection of one 5886 disk drive
enclosure to a single SAS adapter by using a YO cable, go to step 5.
- To perform a connection of two 5886 disk drive
enclosures to a single SAS adapter by using YO cables, where each
enclosure can be attached to an additional 5886 disk drive
enclosure by using an EE cable, go to step 6.
- To perform a connection of two 5886 disk drive
enclosures to a SAS adapter pair by using X cables, where each enclosure
can be attached to an additional 5886 disk drive
enclosure by using an EE cable, go to step 7.
- To perform a connection of one 5886 disk drive
enclosure by using a YI cable to a system with support for a single
SAS drawer, go to step 8.
If your SAS configuration requirements are not supported by
any of these options, go to step 9.
- Perform the connection of one 5886 disk drive
enclosure (A) to a single SAS adapter (C) by
using a YO cable (B) as shown in Figure 1.
Figure 1. Connection of one 5886 disk drive
enclosure to a single SAS adapter by using a YO cable
Go to step 9.
- Perform the connection of two 5886 disk drive
enclosures (A and C) to a single SAS adapter (I) by
using YO cables (G and H), where each enclosure
can be attached to an additional 5886 disk drive
enclosure (B and D) by using two EE cables (E
and F) as shown in Figure 2.

enclosure by using two EE cables
Go to step 9.
- Perform the connection of two 5886 disk drive
enclosures (A and C) to a SAS adapter pair (I) by
using X cables (G and H), where each enclosure
can be attached to an additional 5886 disk drive
enclosure (B and D) by using two EE cables (E
and F) as shown in Figure 3.

- Perform the connection of one 5886 disk drive
enclosure (A) by using a YI cable (B) to
a system with support for a single SAS drawer (C) as
shown in Figure 4.

- For additional information to plan or complete your
SAS cable installation, see Serial-attached SCSI cable planning.
Remember: - Connect power cables and apply power to the 5886 disk drive
enclosure.
- Add the disk drives to the operating system you are using.
- Verify the new configuration. To verify that the system or logical
partition recognizes the disk drive enclosure, see Verifying the installed part.
