Sun Storage Common Array Manager (CAM): Applying Patch 147416-02/147419-02 May Cause Alarm "Lost out-of-band communication" (Doc ID 1598709.1)

Last updated on NOVEMBER 10, 2020

Applies to:

Sun Storage 2540-M2 Array - Version Not Applicable and later
Sun Storage Common Array Manager (CAM) - Version 6.9 to 6.9 [Release 6.0]
Sun Storage 2540 Array - Version Not Applicable and later
Sun Storage 2530 Array - Version Not Applicable and later
Sun Storage 6580 Array - Version Not Applicable and later
Oracle Solaris on SPARC (64-bit)
Oracle Solaris on x86-64 (64-bit)

Symptoms

Applying Solaris patch 147416-02 (sparc) or patch 147419-02 (x86) to Sun Storage Common Array Manager (CAM) version 6.9.0 may cause registered arrays to present an alarm stating that out-of-band (oob) communication has been lost, and report the health status of the array as "Lost Communication"

Example alarm :

Out-of-Band communication with the array has not actually been lost, and some components of CAM will still work correctly for the array, however some functionality provided by the Fault Management Service (FMS) will not work correctly. For example collection of supportdata outputs will fail, and pages will be missing from Service Advisor.

Registration of new arrays may also fail - see <Document 1638927.1>: Sun Storage Common Array Manager (CAM) : Array Registration may fail in version 6.9.0.20 on Solaris

Changes

The problem arises after patch 147416-02 (sparc) or 147419-02 (x86) has been applied to a Solaris install of CAM 6.9.0
