Symptoms
The cluster configuration file can be lost or corrupted, resulting in the out-of-band cluster management IP reverting to the default value.
Impact
Management IP reverts to 192.168.1.246, resulting in loss of access to the chassis through the out-of-band management network.
Conditions
Unexpected system restart while the configuration file is being updated may cause the file to become corrupted. If this occurs, the following error will be logged during blade startup:
"err clusterd[8171]: 013a0027:3: Chassis has N slots, config file has 0, ignoring config file"
Where "N" is the number of physical slots in the chassis (2, 4, or 8).
Workaround
If this occurs, the management IP can be restored using TMSH or the UI through an in-band self IP, or with TMSH through the management console port.
Fix Information
The configuration file update logic has been changed to prevent file corruption during update.
