Compaq Parallel Database Cluster Model PDC/O2000 for Oracle8i and Windows 2000 Administrator Guide
Power Sequencing
Be sure to power up the cluster components in the following order:
1.
RA4000/RA4100 Arrays
2.
Storage Hubs, FC-AL Switches, or Fibre Channel SAN Switches
(Power is applied to Storage Hub when the AC power cord is
plugged in.)
3.
Ethernet hubs or switches
4.
ProLiant servers
Be sure to power down the cluster components in the following order:
1.
ProLiant servers
2.
Ethernet hubs or switches
3.
Storage Hubs, FC-AL Switches, or Fibre Channel SAN Switches
(Power is applied to Storage Hub when the AC power cord is
plugged in.)
4.
RA4000/RA4100 Arrays
Shutting down and powering off the servers first allows them to perform tasks
such as flushing queued database write transactions to disk and properly
terminating running processes.
