Re: What is the purpoese of Master MP and Slave MP card.
I don't think there is an other reason besides the failover function described in the quickspecs;
http://h18000.www1.hp.com/products/quickspecs/12697_div/12697_div.HTML
Management Processor Failover
Management Processor: The Management Processor (MP) is a dedicated processor that simplifies and extends system management, as well as, enhances serviceability. The MP feature set was designed to minimize/eliminate the need for the System Administrator to be physically at the system to perform tasks such as diagnostics, system management, or even hard resets. The MP in the rp8440 can be configured to failover to a secondary MP (again provided two core I/O board sets are installed).
Regards,
Robert-Jan

Re: What is the purpoese of Master MP and Slave MP card.
The MP cards on the rp84xx have MP functions and core IO functions combined.
The rp74xx had a seperate core IO card, for which you would in fact have 2 if you had >1 nPars on the system.
The rp84xx doesn't have a seperate card, so if you have > 1 nPars then you need the extra MP card.

Re: What is the purpoese of Master MP and Slave MP card.
I have found my answer which is as follows:
When the server is configured with one core I/O board, that board must be in slot 0, since the master MP is
always the MP on the core I/O board in slot 0.
When the server is configured for two partitions, it must contain two core I/O boards, one for each partition. It will also contain two MPs. In this case, the MP in slot 0 is the master MP and provides all of the server management functions. The MP on the core I/O board in slot 1 is a slave MP and redirects the operating system gettys to the master MP over an internal MP-to-MP link. All external connections to the MP must be to the master MP in slot 0. The slave MP ports will be disabled.
For high availability (HA), the server powers up and powers down without an MP. Booting HP-UX without an MP depends on the ability of the operating system to boot without a console getty. Thus, in a two-partition system, the partition with a failed MP might not boot, since the MP provides the console getty.
The server configuration cannot be changed without the MP.
In the event of a master MP failure, the slave MP automatically becomes the master MP.

Re: What is the purpoese of Master MP and Slave MP card.
I'm implementing an OpenVMS solution to two RX7640. Each RX7640 has two cells with two MP. I'm doing of acceptance and failover for the whole installation.
I understood the last reply that it's not necessary to synchronized data between master and slave MP. Is it rigth?
My customer would like to do MP failover test. Does anyone know how i can to do this?
thanks

Re: What is the purpoese of Master MP and Slave MP card.
This is the wrong forum for Integrity. You should open a new thread in Servers > Integrity, unless you think the OpenVMS forum would be better.
(You should also create your own thread so you can assign points.)
