The SPARC M8-8 and SPARC M7-8 servers with two PDomains have two SPs (SP0 and SP1), one for each static PDomain, and each SP has two SPMs (SPM0 and SPM1). One of the SPs acts as the active PDomain SP to manage tasks for the PDomain. The other SP acts as the standby PDomain SP that assumes the active PDomain SP role in the event of a failure.
The SPARC M8-8 and SPARC M7-8 servers with one PDomain have a pair of redundant SPs (SP0 and SP1) with a single SPM (SPM0) on each SP. One of the SPs functions as the Active SP to manage the platform, and the other acts as a Standby SP that assumes the Active SP role in the event of a failure.
Both SPs are individually accessible from the external network, so they need to be configured separately with unique IP addresses. As part of failover, the IP address assigned to an Active SP migrates to the new Active SP, depending on which SP is controlling the chassis. To enable you to connect to this IP address to manage the chassis, instead of accessing SP0 or SP1 separately, you must configure the IP address for the Active SP.
The SPARC M7-16 server switch chassis has one pair of SPs with one SPM per SP, and each CMIOU chassis has a pair of SPPs with two SPMs per SPP. This server is capable of supporting up to four PDomains. One of the SPPs on each PDomain is identified as a PDomain SPM, and it is responsible for managing tasks for the PDomain and hosting the rKVMS service for the PDomain.
To enable rKVMS access to a PDomain on a SPARC M7 server, you need to configure the SPM network settings for that PDomain (see Configure the Host IP Address for rKVMS).
Since the Oracle ILOM Remote System Console Plus is not available on SPARC M8-8, the SPM for the PDomain does not need an IP address. However to enable direct access to a PDomain on a SPARC M8-8 sever through Oracle ILOM Remote System VNC Console, you should configure the network settings for the PDomain SPM.
PDomain SPMs are also accessible from the external network if you have configured IP addresses for them.
