Error description
In an error condition that warrants an IBM Spectrum Protect for Space Management failover in a Spectrum Scale cluster, the mmaddcallback variable %eventNode[.qualifier] is populated by Spectrum Scale with a list of 1 or more failed Spectrum Scale cluster nodes. 'dsmmigfs' is unable to correctly process this list if it includes more than 1 node. This might lead to unsuccessful failover with the typical message in dsmerror.log: ANS9450W dsmmigfs : No eligible filesystem for takeover. Product versions affected: Spectrum Protect for Space Management clients versions 7.1.x and 8.1.x running on AIX GPFS and Linux GPFS platforms Initial impact: Medium Additional keywords: 08161,660,706 HSM GPFS TSM LTFS
