We are using 9.1.,

We have a set up like a master and 2 standby servers. M -- > S1,S2 . Both
standby S1 and S2 share the same archive. Master will have an Virtual IP.
Both stand by servers will be replicated using this virtual ip.

Assume the master fails,using our heart beat mechanism Virtual IP bound to
S1(if S1 is ahead or equal to S2 XLOG).,

Is it required to copy the time line history file that is generated at time
of S1 promotion as master to the archive directory of S2 for replication to
work (i.e S1(new master) to S2.)

Without doing this history file copy from S1 to S2, S2 keeps throwing the
following error message.,
