Cluster messages

Syslog messages

Where syslog messages appear  Top

Syslog messages appear by default in the /etc/messages file. For additional information about syslog messages, see Configuring message and event logging.

Troubleshooting syslog messages  Top

The following syslog messages are messages that you can take steps to address. By default they appear on the system console.

Message

Explanation

What you do

cf.timed.enable: timed 
requires java which is 
not enabled on this 
system

Essential Java files are missing from the filer.

Follow these steps:

  1. Install the Java .zip files from the distribution CD-ROM onto the /etc/java directory of your filers.
  2. Reboot.
Interconnect is down

The cluster interconnect is not working properly. Takeover capability is disabled.

Follow these steps:

  1. Check the cluster interconnect cables to make sure that they are seated properly.
  2. If the connections are secure and the message returns, check for cluster interconnect adapter messages in the /etc/messages file, then contact Network Appliance Technical Support.
No disks were detected 
on Fibre channel port 
B; this filer will be 
unable to takeover 
correctly.

The B-port loop has not been connected to the local filer, which means that the local filer cannot take over its partner.

Follow these steps:

  1. Check the B-port loop connections to the partner's disk shelves and make sure that they are securely connected.
  2. Verify that the LRC cards are properly seated.
Root volume volume, 
RAID group n is 
missing n disks and is 
unusable.

A disk shelf or adapter failed, or the root volume's disks might be spread between A-port and B-port loops.

Check the disk shelves and make sure that they are connected properly.

Volume volume is 
missing a data disk 
and has dirty parity.

The filer is refusing to perform a giveback because a volume is in degraded mode with dirty parity.

Caution
You can lose data if you perform a giveback with a volume that is missing a data disk and has dirty parity.

Follow these steps:

  1. Wait until one of these events happen:
    • Parity is clean.
    • The data disk is reconstructed.
  2. Use the sysconfig -r command to verify that one of the events in Step 1 has happened.
  3. Perform a giveback.
Volume volume is 
missing n disks from 
RAID group n and is 
being taken offline 
for this boot.

The volume's disks might be spread between A-port and B-port loops.

Follow these steps:

  1. Verify that the disk shelves are wired properly.
  2. Reboot the filer to clear this condition.
WARNING cluster 
monitor fast timeout 
was blocked for n 
secs.

The Data ONTAP kernel is supposed to schedule the cluster monitor's fast timeout thread at regular intervals to ensure that mailbox data is read and written within specific time frames. If a filer does not receive the mailbox data because the fast timeout thread is blocked, it might assume that its partner is down and attempt to perform a takeover.

If this message happens frequently, gather system utilization data (sysstat, profiling data, and so on), then contact Network Appliance Technical Support so that they can characterize the system.

X link is down.

The cluster interconnect has detected a failure in one of its two communication channels.

This circumstance does not disable takeover but deserves investigation.

Note
This circumstance can also occur temporarily during the booting of a clustered filer.

Check the X (top) cable connections to make sure that the cables are seated properly.

Y link is down.

The cluster interconnect has detected a failure in one of its two communication channels.

This circumstance does not disable takeover but deserves investigation.

Note
This circumstance can also occur temporarily during the booting of a clustered filer.

Check the Y (bottom) cable connections to make sure that the cables are seated properly.
