Starting the U2000 Server in a Solaris High Availability System

The U2000 server can be started in three steps: power on the server safely, start the database, and start the U2000 server processes.

1.2.4.1 Powering On the Server Safely

This topic describes how to power on the server in a HA system (Solaris) safely. The procedure for powering on a server varies according to the server type and disk array type.

Netra T4-1/Netra T4-2/Oracle T4-1/Oracle T4-2/T5220 Server

1. Power on a Netra T4-1/Netra T4-2/Oracle T4-1/Oracle T4-2/T5220 server.

NOTICE

l Oracle SPARC T4-2 workstations support only 200 ~ 240 VAC input voltage and do not support 100 ~ 120 VAC input voltage.

l Netra T4-1/Oracle T4-1/T5220/M4000/M5000 server supports 200 to 240 VAC and 100 to 120 VAC input voltage.

l Netra T4-2 server supports100 to 220 VAC input voltage.

l Configure power supply based on the rated system power requirement, see U2000 Hardware Installation Guide (Huawei N610E cabinet). If the power supply is insufficient, the server automatically stops and the high availability system fails to trigger an active/standby switchover.

2. Wait about 2 or 3 minutes. Then switch on the power of the Netra T4-1/Netra T4-2/Oracle T4-1/Oracle T4-2/T5220 workstation to start the server.

3. After the server is started, check indicators on the front panel. If the power indicator is steady green, the server is powered on. If another indicator is on or blinks, the server does not function properly. Contact the server maintenance engineers to solve the problem. The following figure shows the positions of the power switch and power indicator.

NOTE

l If the Solaris OS starts automatically on the server, the Solaris OS has been correctly installed.

l If the server displays the OK prompt, enter boot. If the server does not respond, no Solaris OS has been installed on the server.

M4000/M5000 Server

1. Power on an M4000/M5000 server.

NOTE

Configure power supply based on the rated system power requirement, see U2000 Hardware Installation Guide (Huawei N610E cabinet). If the power supply is insufficient, the server automatically stops and the high availability system fails to trigger an active/standby switchover.

This issue occurs frequently for the M4000/M5000 with high power consumption.

2. Insert the key delivered with the server into the key slot in the front panel of the M4000/

M5000 server, and turn the rotary switch to the Locked position labeled with , as shown in the following figure.

3. Press the power switch of the workstation, which is identified by . Wait 2 to 3 minutes.

If front indicator of the server is on (changes to steady green), the server starts up and performs self-diagnosis.

NOTE

l Ensure that the green LED power indicator on the operation panel is lit.

l During the power-on process, it is recommended that you use a PC to log in to the controller on an M4000/M5000 server through a serial interface and enter console -d 0 -f to view the server start status.

l If the Solaris OS starts automatically on the server, the Solaris OS has been correctly installed.

l If turn the rotary switch to the Service position labeled with , the server cannot access the OS automatically, the server displays the ok prompt. Enter boot. If the server does not respond, no Solaris OS has been installed on the server.

Disk Array

NOTICE

l To prevent data loss, do not remove or insert disk modules, controllers, fibers, network cables, or serial cables when powering on a disk array.

l To prevent disk damage and data loss, do not turn on or cut off the power supply when the disk is accessing data. If the power supply is cut off, wait at least 1 minute before turning it on.

Power on a disk array.

Power-on Sequence For OceanStor S3900:

l Normal power-on sequence: switch on the power switches of the external power supplies connected to all the devices → press the power button on either controller → switch on the LAN switch or FC switch (if any LAN switch or FC switch is deployed but is not powered on) → switch on the application server (if the application server is not powered on).

l Normal power-down sequence: stop the services of the application server → hold the power button for 5 seconds on either controller → disconnect the controller enclosure and disk enclosures from the external power supplies.

For OceanStor S2600:

l Power-on sequence: cabinet → disk enclosures → controller enclosure → switch (if has)

→ application server.

l Power-off sequence: application server → switch (if has) → controller enclosure →disk enclosures → cabinet.

NOTE

Power supply must be provided for the two power modules of the OceanStor S2600 and OceanStor S3900; otherwise, the OceanStor S2600 and OceanStor S3900 fail to be used. Then press the power switch on the controller A / B. Wait 5 to 10 minutes until the power indicator is steady green, no longer flashing, indicating the success of the power-on.

Physical indications that the storage system is up and running without error:

l The power indicators of the controllers, controller enclosure, and disk enclosures are steady green.

l The alarm indicators of the controllers, controller enclosure, and disk enclosures are off.

l The running indicators of the coffer disks are steady green, and their alarm/location indicators are off.

1.2.4.2 Starting the Database

This topic describes how to start the database in a Solaris high availability system. The U2000 can start properly only after the database is started.

Prerequisites

l The OS has been started.

l The server is properly connected to the network.

l The VCS service must be properly started. The VCS service has started along with the OS and the disk is functioning properly.
