Issue:

The SpectroSERVER's SNMP stack hangs and causes the following problems:

Online Backup (OLB) failures

SNMP requests are ignored

Updated SNMP communications are missed

False Management Agent Lost alarms are generated

Inability for the SS process to stop

Cause:

This was due to code issues in the SpectroSERVERs SNMP layer.

Resolution:

This is resolved in 10.2.1 and in the following patches for releases prior to 10.2.1:

10.2.0 - Spectrum_10.02.00.PTF_10.2.020*

(*This patch also includes a fix for SDM/SDC.)

10.1.2 - Spectrum_10.01.02.D101h

10.1.1 - Spectrum_10.01.01.D76j

 

The release notes show the following:

 

 Symptom: Rare but consistent SpectroSERVER hangs due to multiple problems with the SNMP subsystem. 

        Symptoms can include failed online backups, failed shutdowns and invalid management agent lost alarms.

 

        Resolution: Major overhaul of SNMP subsystem, designed to improve efficiency and stability.
