Complete the following steps to connect the 5887 disk drive
enclosure to one or more Serial-attached SCSI (SAS) adapters,
to a system with support for a SAS disk drawer, or to a PCIe storage
enclosure with support for a SAS disk drawer.
For additional
information related to SAS cabling and cabling configurations, see Serial-attached SCSI cable planning.
- If the system is powered on, you must do one
of the following actions, depending on the supported functions of
your operating system:
- Unconfigure the adapters to which you are connecting the 5887 disk drive
enclosure.
- Power off the adapters to which you are connecting the 5887 disk drive
enclosure.
- Power off the logical partitions or systems that own the adapters
to which you are connecting the 5887 disk drive
enclosure.
To do one of these required actions, choose one of the following
options.Important: If you are connecting to two SAS adapters
or to the two internal RAID controllers of a PCIe storage enclosure,
both of the SAS adapters or RAID controllers must be powered off or
unconfigured.
- Confirm the factory-set mode of the 5887 disk drive
enclosure by using information printed on stickers at the rear of
the enclosure. Stickers are attached to the lower-left shelf of the
chassis (A) and the center support between
the enclosure services manager (ESM) modules (B).
The stickers indicate whether the enclosure is set to mode 1, mode
2, or mode 4, as shown in Figure 1.

5887 disk drive enclosure
- Confirm that all adapters that you need
to connect to the 5887 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 5887 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.

in the 9117-MMB, 9117-MMC, 9117-MMD, 9179-MHB, 9179-MHC, or 9179-MHD.
- Confirm the configuration that you will
use to cable the SAS adapter to the 5887 disk drive
enclosure as follows:
- See the common SAS adapter configurations that are listed in step 7 to determine if one of them
applies to your requirements.
- To learn about other specific SAS adapter configurations for the 5887 disk drive
enclosure, see SAS cabling for the 5887 drawer.
- Locate the connection for each adapter for which you
are using an external SAS cable to connect the 5887.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
7 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 3.
- The external port of an internal adapter cable that you confirmed
in step 4.
- Choose one of the following options to cable the SAS
adapter.
Note: Adapters
are cabled to the
5887 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.
If your SAS configuration requirements are not supported by
any of these options, go to step 18.
