Setting the Fibre Channel port mapping: 2145-SV1

Determining adapter slot locations

In most cases, you can use one of the standard port mappings when you are replacing a SAN Volume Controller 2145-DH8, SAN Volume Controller 2145-CF8, or 2145-CG8 node.

Table 1 describes the standard port mapping on a 2145-SV1 node. To use the table, locate the row that fully describes the location and type of Fibre Channel (FC) and Ethernet adapters in your existing node. If you set the pre-defined port mapping in the -fcportmap column, you must install the appropriate adapters in the slot locations that are shown in the2145-SV1 columns. You can also install more adapters in the unused slots of the new node.

Determining the port mapping

The following sections describe how to determine the individual port mappings that are listed in Table 1. The name of each section represents the value that you should specify on the -fcportmap parameter of the chvpd command.

In each table, the new_adapter_location and new_adapter_port_id values are the adapter slot and port numbers in the 2145-SV1 node that will be assigned the port mask position (fc_io_port_id) and WWPN value. You can also set port mappings for adapters that are not yet installed in the 2145-SV1 node. These mappings take effect if an adapter is later installed in that slot location. Each table shows one of the standard mappings and the chvpd command that is required to set the port mapping.

Port map default

To establish this port map on the 2145-SV1 node, enter one of the following chvpd commands.

satask chvpd -wwnn 500507680x0xxxxx -fcportmap default

or 

satask chvpd -wwnn 500507680x0xxxxx -fcportmap 31-11,32-12,33-13,34-14,41-21,42-22,43-23,44-24,61-31,62-32,63-33,64-34,71-51,72-52,73-53,74-54

Port map dh8:0+4

Use this mapping if the existing 2145-DH8 node has slot 1 empty and a 4-port Ethernet adapter that is installed in slot 2.

The existing four ports are mapped to the four ports in slot 3 of the 2145-SV1 node. If you install a 4-port adapter in slot 4 of the 2145-SV1 node, the ports take the WWPN values that would have been used by slot 1 of the 2145-DH8 node.

To establish this port mapping on the 2145-SV1 node, enter one of the following chvpd commands.

Port map dh8:2+2:801

The existing four ports from the two FC adapters are mapped to the four ports in slot 3 of the 2145-SV1 node. If a 4-port adapter is installed in slot 4 of the 2145-SV1 node, it takes the unused WWPN values from slots 1 and 2 of the 2145-DH8 node.

Setting the mapping manually

The fcportmap value is built from the slot and location of each port in the 2145-SV1 node and the slot and port locations from the existing node. To manually set the port mapping, perform the following steps.

1. On the node that you are upgrading, issue the lsportfc command.

   The system displays detailed information about the existing ports on the node. Table 19 shows example output from a node that has a 4-port Fibre Channel adapter in slot 1 and a 2-port Fibre Channel adapters in slots 2 and 5.

   Table 19. Example output from the lsportfc command

   IBM_2145:cluster:superuser>lsportfc -filtervalue node_id=2 id fc_io_port_id port_id type port_speed node_id node_name WWPN nportid status attachment cluster_use adapter_location adapter_port_id 16 1 1 fc 8Gb 2 node2 500507680140BADF 010400 active switch local_partner 1 1 17 2 2 fc 8Gb 2 node2 500507680130BADF 020400 active switch local_partner 1 2 18 3 3 fc 8Gb 2 node2 500507680110BADF 010500 active switch local_partner 1 3 19 4 4 fc 8Gb 2 node2 500507680120BADF 020500 active switch local_partner 1 4 20 5 5 fc 8Gb 2 node2 500507680150BADF 010600 active switch local_partner 2 1 21 6 6 fc 8Gb 2 node2 500507680160BADF 020600 active switch local_partner 2 2 22 7 7 fc 8Gb 2 node2 500507680158BADF 010700 active switch local_partner 5 1 23 8 8 fc 8Gb 2 node2 500507680168BADF 020700 active switch local_partner 5 2

2. Record the adapter_location, adapter_port_id, and WWPN values for each fc_io_port_id that is displayed in the lsportfc output.
   In Table 20, the appropriate values from Table 19 are shown in columns C, D, and WWPN.

   Table 20. Record the location of adapter slots and ports on the original node

   fc_io_port_id	New 2145-SV1		Existing Node		WWPN
   	adapter_location  A	adapter_port_id  B	adapter_location  C	adapter_port_id  D
   1			1	1	500507680140BADF
   2			1	2	500507680130BADF
   3			1	3	500507680110BADF
   4			1	4	500507680120BADF
   5			2	1	500507680150BADF
   6			2	2	500507680160BADF
   7			5	1	500507680158BADF
   8			5	2	500507680168BADF

3. Ensure the 2145-SV1 node is fitted with at least the same number of Fibre Channel and Ethernet ports as the existing node.

   In this example, the 2145-SV1 node has two 4-port Fibre Channel adapters in slots 3 and 4.

4. Record the slot numbers and port numbers that are used in the 2145-SV1 node.

   In Table 21, the adapter_location and adapter_port_id values for the 2145-SV1 node are added to columns A and B.

   Table 21. Add the location of adapter slots and ports on the 2145-SV1 node

   fc_io_port_id	New 2145-SV1		Existing Node		WWPN
   	adapter_location  A	adapter_port_id  B	adapter_location  C	adapter_port_id  D
   1	3	1	1	1	500507680140BADF
   2	3	2	1	2	500507680130BADF
   3	3	3	1	3	500507680110BADF
   4	3	4	1	4	500507680120BADF
   5	4	1	2	1	500507680150BADF
   6	4	2	2	2	500507680160BADF
   7	4	3	5	1	500507680158BADF
   8	4	4	5	2	500507680168BADF

5. Enter the chvpd command to create the port mapping. Specify the slot and location of each port in the 2145-SV1 node, followed by the slot and location of each port in the existing node, in the form AB-CD,AB-CD.

   satask chvpd -wwnn 500507680100BADF -fcportmap AB-CD,AB-CD,AB-CD,AB-CD,AB-CD,AB-CD

   For example, the following command uses the information that was recorded in Table 21.

   satask chvpd -wwnn 500507680100BADF -fcportmap 31-11,32-12,33-13,34-14,41-21,42-22,43-51,44-52 

6. Optionally, you can add mappings for more ports that might be installed on the 2145-SV1 node in the future.

Template to manually set fcportmap values

You can use Table 22 to record information about the existing node and the new 2145-SV1 node.
