1910169 - How to handle HANA Alert 26: ‘Unassigned volumes’


When a volume is not assigned to a service (nameserver, indexserver, statisticeserver, xsengine) alert 26 gets displayed.

This alert will appear in HANA Studio -> Administrator -> Alerts and service (for example: xsengine) is stopped.



The following trace entry and callstack may be observed in the indexserver :

<date> <time>  e Backup BackupMgrSrc_Container.cpp(00505) : exception 1: no.110029 (Backup/spi/impl/Backup_TopologyService.cpp:71)
Backup is not possible because the volume '1' is not assigned to a service
exception 1: no.110028 (Backup/Manager/impl/Source/BackupMgrSrc_Container.cpp:504)
Orphaned volume with the number '1' found in the topology
