Appendix G High AvailabilityHPSS Installation Guide September 2002 549Release 4.5, Revision 2Note that you do not configure your service adapter. This is because HACMP will changeyour boot adapter into your service adapter when it brings up HPSS. Therefore, withoutHACMP running, you configure the adapter with its boot name and address.6. Add Physical Volume IDs (PV IDs) for all shared hdisks (if necessary)If this is the first time that your shared disks have ever been used, you will need tomanually assign PV IDs to them. To check for this, run lspv. The second column of theoutput should have a big 16-digit hexadecimal number, the PV ID, for each physicalvolume. If no PV ID is shown for certain volumes, you will have to create them yourselfusing the following command for each physical volume (the example assigned a PV ID tohdisk3):% chdev -l ‘hdisk3’ -a pv=’yes’7. Increase the maximum number of allowed logins8. Turn off NetWare if it is installedOne potential problem is an incompatibility between NetWare and HACMP. NetWare willoften keep a network interface busy which will cause attempted adapter swaps to fail. Aneasy test for this problem is to run the following command:% grep rcnetw /etc/inittabIf the command came back with no output, you are fine. Otherwise, you will need tocomment out the offending line in the /etc/inittab.9. Create /etc/environment entrySince DCE’s RPC mechanism will attempt to use any and all configured interfaces, it isimportant to put a RPC_UNSUPPORTED_NETADDRS entry in the /etc/environment fileon both nodes with the IP address of every non-service interface listed. This will force theRPCs to utilize the service interface. For example, our sample configuration from theexample worksheet would require the following entry:RPC_UNSUPPORTED_NETADDRS=192.94.47.244:192.94.47.145:192.94.47.146:192.94.47.147G.4.3 Initial HACMP ConfigurationUsing the information from your worksheets, perform the following steps from either nodes:G.4.3.1 Define a new cluster% smitty clusterCluster Configuration-> Cluster Topology-> Configure Cluster
