GSAN palautettiin äskettäin vahvistettuun tarkistuspisteeseen, ja nyt MCS ei käynnisty. Seurattaessa tmp dpnctl mcs -aloituslähtölokia havaittiin virhe, jonka mukaan gsan-palautusaika ei vastaa tallennettua palautusaikaa.
Tämä voi päteä, kun NetWorker VMware Protection -integrointi on määritetty VBA (Virtual Backup Appliance)- tai IDPA-laitteiden (Integrated Data Protection Appliance) tai minkä tahansa Avamar Serverin kanssa.

MCS:n ja GSAN:n aikaleima ei ole käytössä, koska GSAN palautettiin aiempaan ajankohtaan.
- Pakota MCS-palautus niin, että MCS ja GSAN synkronoidaan.
