Appendix G High Availability
HPSS Installation Guide September 2002 549
Release 4.5, Revision 2
Note that you do not configure your service adapter. This is because HACMP will change
your boot adapter into your service adapter when it brings up HPSS. Therefore, without
HACMP 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 to
manually assign PV IDs to them. To check for this, run lspv. The second column of the
output should have a big 16-digit hexadecimal number, the PV ID, for each physical
volume. If no PV ID is shown for certain volumes, you will have to create them yourself
using the following command for each physical volume (the example assigned a PV ID to
hdisk3):
% chdev -l ‘hdisk3’ -a pv=’yes’
7. Increase the maximum number of allowed logins
8. Turn off NetWare if it is installed
One potential problem is an incompatibility between NetWare and HACMP. NetWare will
often keep a network interface busy which will cause attempted adapter swaps to fail. An
easy test for this problem is to run the following command:
% grep rcnetw /etc/inittab
If the command came back with no output, you are fine. Otherwise, you will need to
comment out the offending line in the /etc/inittab.
9. Create /etc/environment entry
Since DCE’s RPC mechanism will attempt to use any and all configured interfaces, it is
important toput a RPC_UNSUPPORTED_NETADDRS entry in the /etc/environment file
on both nodes with the IP address of every non-service interface listed. This will force the
RPCs to utilize the service interface. For example, our sample configuration from the
example worksheet would require the following entry:
RPC_UNSUPPORTED_NETADDRS=192.94.47.244:192.94.47.145:192.94.47
.146:192.94.47.147
G.4.3 Initial HACMP Configuration
Using the information from your worksheets, perform the following steps from either nodes:
G.4.3.1 Define a new cluster
% smitty cluster
