Make a note of the srvnetname for the SYB_HACMP entry in sysservers. When it is configured for Sybase Failover, SYB_HACMP points to the companion server’s svrnetname (for example, the srvnetname for the SYB_HACMP entry on companion server MONEY1 is PERSONNEL1).
Run dbcc ha_admin to move the companion to single-server mode:
dbcc ha_admin (' ', 'state_machine', 'halt')
Where ' ' is used as an empty placeholder.
Re-run installhasvss. After installhasvss finishes, the companion server reverts to its original mode.
If the node crashes after you perform step 2, above, the srvnetname of the remote server is removed from sysservers. If this occurs, add the name of the remote server to sysservers by issuing:
sp_addserver SYB_HACMP, null, 'remote_server_svrnetname'
Run dbcc ha_admin to return the companion server to its original mode:
dbcc ha_admin (' ', 'state_machine', 'restart')
