3 Congure the Maximum Disk Usage value and click Finish.
4 Start vCenter Server Heartbeat.
Note vCenter Server Heartbeat is a symmetrical system and can operate with either server in the active role.
For this reason, the queue size is always set to the same value for both servers.
MaxDiskUsage Error Messages
The following error messages display when available disk space on the servers is exceeded.
[L9]Exceeded the Maximum Disk Usage
(VCChannelExceededMaxDiskUsageException)
This message indicates that you have exceeded the amount of allocated disk space reserved for the queue..
Problem
vCenter Server Heartbeat exceeds its precongured queue size.
Cause
On the active server, the size of the active server queue has exceeded the disk quota allocated for it. On the
passive server, the size of the passive server queue has exceeded the disk quota allocated for it.
Solution
◆
While neither condition is critical, determine the sequence of events that led to the condition.
[L9]Exceeded the Maximum Disk Usage on the ACTIVE Server
This message indicates that you have exceeded the amount of allocated disk space reserved for the active
server’s send queue.
Problem
Replication stops and the vCenter Server Heartbeat Event Log displays the error message originating from the
active server.
Cause
A temporary interruption in the VMware Channel, or insucient VMware Channel bandwidth to support the
volume of replication trac starts lling the active server queue. The size of the queue eventually exceeds the
congured disk quota.
Solution
◆
Assuming no other channel connection issues exist (see knowledge base article 1008551 (vCSHB-Ref-992)
- Troubleshooting VMware vCenter Server Channel Drops), you can increase the amount of disk space allotted
to the queues. The default setting is 1GB, which can be insucient on servers with a large volume of
replication trac and limited VMware Channel bandwidth. If you have sucient disk space, set the queue
size to zero (unlimited) so vCenter Server Heartbeat can use any free disk space to store the queues.
