About quiescing and unquiescing Enterprise Vault services
In Enterprise Vault 8.0 or later, quiescing and unquiescing is done at the component level.
See About granular quiescence.
In Enterprise Vault 7.5, the mechanism to quiesce and unquiesce is performed at the Enterprise Vault server level through the following Enterprise Vault registry keys:
EnableArchive
EnableCrawler
EnableExpiry
EnableFileWatch
EnablePSTMigrations
EnableReplayIndex
EnableRestore
The locations of the Enterprise Vault registry keys are as follows:
HKEY_LOCAL_MACHINE\SOFTWARE\KVS\Enterprise Vault\Storage
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\KVS\Enterprise Vault\Storage
The following lists provide a high-level overview of how to quiesce or unquiesce the Enterprise Vault services.
To quiesce the Enterprise Vault services, stop the Enterprise Vault services, create the special Enterprise Vault registry keys, and restart the services. Make sure that you create the Enterprise Vault registry keys with a value of zero.
To unquiesce the Enterprise Vault services, stop the Enterprise Vault services, delete the special Enterprise Vault registry keys, and restart the services.
Multiple quiescent and unquiescent jobs can run on the same Enterprise Vault server. Therefore, NetBackup uses a registry counter (NBU_EV_QSE_LEVEL) to track the number of times the Enterprise Vault services are put into read-only mode. If the value of this counter is zero, the Enterprise Vault services are running in a read-write mode. If value of this counter is non-zero, then the Enterprise Vault services are running in a read-only mode.
Note:
Incorrect use of the Windows registry editor may prevent the operating system from functioning properly. You should be very careful when making changes to a Windows registry. Only those who have experience with the registry editor application should attempt to modify the registry. Veritas recommends that you make a complete backup of the registry and workstation before you make any registry changes.
The location of this registry counter is one of the following addresses:
HKEY_LOCAL_MACHINE\SOFTWARE\KVS\Enterprise Vault\NetBackup
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\KVS\Enterprise Vault\NetBackup
