The state of a pool applies only to connections that are actively requesting a server to be used from the pool during login or during failover. Table 2-2 lists possible pool states:
Status |
Description |
|---|---|
PRE_UP |
Mutually-aware-specific pool status. The pool is either in the process of being marked as UP, or has encountered a problem during that process. Check the error log to troubleshoot the problem. After you resolve the problem, manually set the pool status to UP on one of the mutually-aware companion OpenSwitch servers. The command will be propagated to the other OpenSwitch companion if it is running. WARNING! Do not manually set a pool’s status to PRE_UP. |
UP |
The pool is immediately available for use. |
PRE_DOWN |
Mutually-aware specific pool status. The pool is either in the process of being marked as DOWN, or has encountered a problem during that process. Check the error log to troubleshoot the problem. After you resolve the problem, manually set the pool status to DOWN on one of the mutually-aware companion OpenSwitch servers. The command will be propagated to the other OpenSwitch companion if it is running. WARNING! Do not manually set a pool’s status to PRE_DOWN. |
DOWN |
The pool is unavailable, and is not considered for use by any new client connections established to OpenSwitch. |
PRE_LOCKED |
Mutually-aware specific pool status. The pool is either in the process of being marked as LOCKED, or has encountered a problem during that process doing so. Check the error log to troubleshoot the problem. After you resolve the problem, manually set the pool status to LOCKED on one of the mutually-aware companion OpenSwitch servers. The command will be propagated to the other OpenSwitch companion if it is running. WARNING! Do not manually set a pool’s status to PRE_LOCKED. |
LOCKED |
The pool is available, but any new incoming connections actively being connected through the pool are blocked (or stopped) until the status is changed to UP or DOWN. Blocked connections appear to the client applications to have stopped responding until the pool is unlocked. |
SUSPENDED |
The pool is being suspended by OpenSwitch due to a failure that requires an administrator’s manual intervention. See “Invoking custom and manual scripts” for more information. The pool blocks on all new connections until rp_go is issued. WARNING! Do not manually set a pool’s status to SUSPENDED. |
