strange route issue in powerha 5.4?
hi all



we upgraded hacmp(powerha) from 5.2 to 5.4 recently .



during the failover testing, we found a strange network issue. after standby node took service ip address (172.15.100.8) online at standby NIC, we were able to log in the standby node by telnet 172.15.100.8 which stays at standby node standyb NIC.



when we tried to run ping or traceroute to a ip address outside of of our network, for example google.com or ibm.com, the NIC that holds service ip address were not able to send any packet out at all.



instead, the primay NIC that holds boot address of standby node (172.15.103.79) will take in place and send the ping packet out or traceroute to out side of world.



on the other hand, any testing within our intranet acted normal. we checked dns server and routing table of standby node and gateway setup, they were all good.



the follwoing info is the routing configuration from standby node.

as you may see, the default routing is set up for en4 (the primay NIC that holds boot ip address). is it possible that we manally set up a route entry to let en5 ( the standby NIC that will holds the service ip address when failover) go out side as well like this?

wanboot_keygen

wanboot_keygen(1M)					  System Administration Commands					wanboot_keygen(1M)

NAME

       wanboot_keygen - create and display client and server keys for WAN booting

SYNOPSIS

       /usr/lib/inet/wanboot/keygen -c -o net=a.b.c.d ,cid=client_ID,type=3des

       /usr/lib/inet/wanboot/keygen -c -o net=a.b.c.d ,cid=client_ID,type=aes

       /usr/lib/inet/wanboot/keygen -m

       /usr/lib/inet/wanboot/keygen -c -o net=a.b.c.d ,cid=client_ID,type=sha1

       /usr/lib/inet/wanboot/keygen -d -m

       /usr/lib/inet/wanboot/keygen -c -o net=a.b.c.d ,cid=client_ID,type=keytype

DESCRIPTION

       The keygen utility has three purposes:

	   o	  Using the -c flag, to generate and store per-client 3DES/AES encryption keys, avoiding any DES weak keys.

	   o	  Using the -m flag, to generate and store a "master" HMAC SHA-1 key for WAN install, and to derive from the master key per-client
		  HMAC SHA-1 hashing keys, in a manner described in RFC 3118, Appendix A.

	   o	  Using the -d flag along with either the -c or -m flag to indicate the key repository, to display a key of type specified by key-
		  type, which must be one of 3des, aes, or sha1.

       The  net  and cid arguments are used to identify a specific client. Both arguments are optional. If the cid option is not provided, the key
       being created or displayed will have a per-network scope. If the net option is not provided, then the key will have a global scope. Default
       net and code values are used to derive an HMAC SHA-1 key if the values are not provided by the user.

OPTIONS

       The following options are supported:

       -c    Generate  and  store per-client 3DES/AES encryption keys, avoiding any DES weak keys. Also generates and stores per-client HMAC SHA-1
	     keys. Used in conjunction with -o.

       -d    Display a key of type specified by keytype, which must be one of 3des, aes, or sha1. Use -d with -m or with -c and -o.

       -m    Generate and store a "master" HMAC SHA-1 key for WAN install.

       -o    Specifies the WANboot client and/or keytype.

EXAMPLES

       Example 1 Generate a Master HMAC SHA-1 Key

	 # keygen -m

       Example 2 Generate and Then Display a Client-Specific Master HMAC SHA-1 Key

	 # keygen -c -o net=172.16.174.0,cid=010003BA0E6A36,type=sha1
	 # keygen -d -c -o net=172.16.174.0,cid=010003BA0E6A36,type=sha1

       Example 3 Generate and Display a 3DES Key with a Per-Network Scope

	 # keygen -c -o net=172.16.174.0,type=3des
	 # keygen -d -o net=172.16.174.0,type=3des

EXIT STATUS

       0     Successful operation.

       >0    An error occurred.
