HP-UX 가 제공하는 MC-SG설정된 서버의 hostname변경하기 (acc-db1, 2 --> erpdb1, 2)
* 먼저 양서버에서 오라클을 중지 및 crs를 중지한 이후 진행
root@acc-db1[/]#cmhaltcl -fv <-- 클러스터를 중지한다 (양서버에 적용됨)
Disabling all packages from starting on nodes to be halted.
Disabling all packages from running on acc-db1.
Disabling all packages from running on acc-db2.
Warning: Do not modify or enable packages until the halt operation is completed.
Disabling automatic failover for failover packages to be halted.

cmviewcl: Cannot view the cluster configuration: No such file or directory.
Either this node is not configured in a cluster, user doesn't have
access to view the cluster configuration, or there is some obstacle
to viewing the configuration. Check the syslog file for more information.
For a list of possible causes, see the Serviceguard manual for cmviewcl.
