IBM Power 570 and IBM Power 595 (POWER6 ... - IBM Redbooks

For more information, see the following chapters:
► Chapter 2, “IBM Power 570 Model 9117-MMA” on page 41
► Chapter 3, “IBM Power 595 model 9119-FHA” on page 99
Some of the additional hot add or hot repair capabilities are as follows:
► Power supply replacement (procedure slightly different between 9117-MMA and
9119-FHA)
► 9117-MMA Hot-Processor Enclosure (node) Add / Cold-Processor Enclosure (node)
Repair
An additional processor closure can be added, provided that the system has a spare
ordered previously and that unused connectors on the attached Service Interface Cable
and space available in the rack are immediately below the processor enclosure.
► RAID Hot Spare Disk Add
This option allows one or more disk drives on a stand-by (hot spare). If a drive fails, the
second drive is brought online automatically in place of the failed drive. This option
minimizes the time that the array is running unprotected and is available for disk
controllers running either RAID-5 or RAID-6. At least one drive per disk controller is
required for the arrays protected. This protection option is not applicable to mirrored
configurations.
Serviceability
The purpose of serviceability is to repair the system while attempting to minimize or eliminate
service cost (within budget objectives), while maintaining high customer satisfaction.
Serviceability includes system installation, MES (system upgrades or downgrades), and
system maintenance or repair. Depending upon the system and warranty contract, service
can be performed by the customer, an IBM representative, or an authorized warranty service
provider.
The serviceability features delivered in this system provide a highly efficient service
environment by incorporating the following attributes:
► Design for Customer Set Up (CSU), Customer Installed Features (CIF), and Customer
Replaceable Units (CRU)
► Error detection and Fault Isolation (ED/FI)
► First Failure Data Capture (FFDC)
► Converged service approach across multiple IBM server platforms
Service environments
The POWER6 processor-based platforms support two main service environments:
► No Hardware Management Console (HMC).
There are two service strategies for non-HMC systems
– Full system partition: A single partition owns all the server resources and only one
operating system can be installed.
– Partitioned system: In this configuration, the system can have more than one partition
and can be running more than one operating system. In this environment, partitions
are managed by the Integrated Virtualization Manager (IVM), which provides some of
the functions provided by the HMC.
