This chapter discusses diagnostic procedures and failure responses for the
SP-attached server and clustered enterprise server software of PSSP which use
the SAMI (Service and Manufacturing Interface) hardware protocol. The
SP-attached servers and clustered enterprise servers which use the SAMI
hardware protocol include the RS/6000 S70, S7A, and S80 servers and the IBM
pSeries 680. The list of known error symptoms and the
associated responses are in the section Error symptoms, responses, and recoveries. A list of the information to collect before
contacting the IBM Support Center is in the section Information to collect before contacting the IBM Support Center.
SP-attached servers can be connected to SP systems that contain an SP
Switch or those that have no switch. The S80 and the IBM
pSeries 680 servers can also connect to the SP Switch2. Clustered
enterprise servers are clustered with an SP control workstation in a system
that contains no SP node frames. Clustered enterprise server systems
may contain an SP Switch or SP Switch2, in which case they are effectively
treated as SP-attached server systems. In a clustered environment
without a switch, or in a system with an SP Switch2, the system cannot be
partitioned. The terms the server and all servers are
used in this chapter in place of 'SP-attached server or clustered
enterprise server which uses the SAMI hardware protocol' and
'SP-attached servers or clustered enterprise servers which uses the SAMI
hardware protocol' respectively.
For information on diagnosing problems with SP-attached servers or
clustered enterprise servers which use the CSP (Converged Service Processor)
hardware protocol, see Diagnosing System Monitor problems. The SP-attached servers and clustered enterprise
servers which use the CSP hardware protocol include the RS/6000 H80 and M80
servers, and the IBM pSeries 660 (6H0, 6H1, 6M1).
For information on diagnosing problems with SP-attached servers or
clustered enterprise servers which use the HMC (Hardware Management Console)
hardware protocol, see Diagnosing IBM e(logo)server pSeries 690 problems. The SP-attached servers and clustered enterprise
servers which use the HMC hardware protocol include the IBM
pSeries 690.
