Pci-X Ddr 1.5 Gb Cache Sas Raid Adapter (Fc 5908; Ccin 575C) - IBM 8236-E8C Manual

Concurrent maintenance procedure
Concurrent maintenance of this double-wide adapter is not supported through the Hardware
Management Console (HMC). Concurrent maintenance must be done from within the partition operating
system. In IBM i, the Hardware Service Manager (HSM) of the system or owning partition will
automatically power off or on both PCI slots when either slot is selected. In AIX or Linux, you must
manually power off and on each slot separately.
Important:
v Both PCI slots must be powered off when installing or removing this adapter with the system power
on.
v If this adapter is the load source IOA, or any other storage IOA with critical DASD attached for the
system, this concurrent maintenance procedure should be performed by a qualified service provider.

PCI-X DDR 1.5 GB cache SAS RAID Adapter (FC 5908; CCIN 575C)

Learn about the specifications and operating system requirements for the feature code (FC) 5908 adapter.
Overview
The PCI-X DDR 1.5 GB cache SAS RAID Adapter is a SAS disk controller with a maximum of 1.5 GB
compressed write cache and a maximum 1.6 GB compressed read cache. Auxiliary write cache and
concurrent battery maintenance are provided. The controller is implemented using two physical adapters
that are securely connected to form a double-wide adapter. The double-wide adapter requires two
adjacent Peripheral Component Interconnect-X (PCI-X) slots. The auxiliary write cache side of the
double-wide adapter contains a dual, concurrently maintainable cache battery pack which maintains
cache memory on both adapters in the event of an abnormal termination.
When used in a logical partition (LPAR) environment, this double-wide adapter must have both slots of
the adapter assigned to the same logical partition. When implementing dynamic LPAR (DLPAR), both
slots of the adapter must be managed together. Feature 5908 indicates a gen-3 blind swap cassette. This
feature is used in the 5790 and 5796.
575C is the CCIN number on the write-cache adapter.
