NAME : HCPNETBK DESCRIPTION: *NETWORK Request Block DSECT : NETBK FUNCTION : Map the communication control blocks used by the *NETWORK Socket *NETWORK Request Block +----------------> +-------------------------+ | Fixed Common | Sender Common Info | | *NETWORK +-------------------------+ | Header | Reply Common Info | +----------------> +-------------------------+ | | | | Operation Code | SEND | | Specific Area | or | | | REPLY | | (variable size) | Area | | | | | Up to 128 Pages . . | . . | | | +----------------> +-------------------------+ The *NETWORK control block is divided into two sections. A fixed header portion which contains a sender and a reply section. The sender area contains common information related to the task sending the request. Whereas the reply area contains common information related to a task replying to a SEND_REQUEST with a synchronous reply it received from another system using HCPSOCK SEND_REPLY. The second section is a operation code specific area which is mapped differently per *NETWORK operation code. This area can be mapped differently depending on whether it is a HCPSOCK SEND_REQUEST or SEND_REPLY. Reference the DSECT for a specific operation code for the appropriate data mappings. REATED - By calling HCPNETGB ELETED - By calling HCPNETRB ODIFIED - By calling HCPNETAB to add additional 4K pages NCHORED - N/A RELOCATION CONSIDERATIONS : None COMMENTS : - The following tags are used to described the address type for pointers within this control block: A : Host absolute address R : Host real address L : Logical address in the system execution space G : Guest absolute address

This *NETWORK request will verify this system's MACPREFIX and USERPREFIX settings follow the rules before allowing it to become an active member of the SSI. The Verify MAC Prefix request will send this system's current MACPREFIX and USERPREFIX to all SSI members. The SSI members receiving this request will verify that the MACPREFIX in the request doesn't match their MACPREFIX and the USERPREFIX does match their setting. If both MAC prefix values are acceptable, then an affirmative reply will be returned to this system. Otherwise a negative reply is returned. Operation Code Specific Return Codes: None Format: 0

The receiving SSI member{s} will check to see if the specified MAC Address in the SEND_REQUEST is in use on their system. If the MAC Address is not found, an affirmative respones via a SEND_REPLY is returned in the response area of common *NETWORK header indicating the address is not in use. An unanimous affirmative response from all the active members will allow the issuing system to network device to be defined, attached to a guest or the Diagnose x26C Subcode 30 MAC Service to complete successfully. Conversely a negative response from any system will prevent the network device from being added to the guest's virtual configuration. Optional Prefix Check (NE1FLAGS.NE1PFXCK = ON) ***************------ If NE1FLAGS.NE1PFXCK is ON, then an additional MAC PREFIX check will be performed by each SSI member. In addition to testing whether the specified 6 byte MAC Address is allocated, it will also verify that the MAC PREFIX (first 3 bytes of the MAC Address) doesn't match its currently set SYSTEM, USER or ENSEMBLE PREFIX settings. If the MAC PREFIX is the same as an SSI Member, that member will return a negative response. This test is necessary in order to verify a 6 byte explicit user MAC Address assignment by a customer or guest will never conflict with a system MAC assigned by any SSI member. 2) Release MAC Request A "Release MAC Request" multicast will be sent from an active SSI member to all other active members when it is done using a foreign assigned MAC on his system. This will allow the system image which created (owns) the MAC Address to mark it as available for reuse in his Assigned MAC MLT. When a system receives a "Release Foreign MAC Request", it will verify the user which owns the MAC Address is not locally owned prior to removing the MAC from his Assigned MAC MLT. This prevents the MAC Address from being removed when a release request occurs in the middle of a live guest migration. If the migration fails fails, the guest will not be relocated and it will remain running. Notes : The receiving system will NOT REPLY to this request with a SEND_REPLY. 3) Confirm MAC Address Allocation A "Confirm MAC Address Allocation" multicast is sent out by this system to all other active SSI members within the cluster to confirm the allocation of a MAC Address by his system. This allows the other SSI members to keep track of user defined or MAC Address which they own that are currently in use by network devices on this system. This request is broadcast whenever a user defined or a foreign MAC Address is allocated on this system image. Notes : The receiving systems will NOT REPLY to this request with a SEND_REPLY.

An "Assigned MAC Table Synchronization" request is sent to each active member of the SSI when a system joins a SSI. At SSI JOIN time, both the candidate and target systems will synchronize MAC Addresses matching the candidate and target system and user's MACPREFIXs. This will involve multiple send with reply requests from each active member of a SSI. The SEND_REQUEST sends the data below to the target system.
