Yesterday, like any other patch day, i updated a few hosts to latests patches from VMware for ESXi.
After the updates veeam backups failed for vm on patched hosts with:
10/8/2015 4:53:36 AM :: Processing server01 Error: NFC storage connection is unavailable. Storage: [stg:datastore-34156,nfchost:host-10319,conn:vcenter01]. Storage display name: [vDisk-SAS-03].
Failed to create NFC download stream. NFC path: [nfc://conn:vcenter01,nfchost:host-10319,stg:datastore-34156@server01/server01.vmx].
VMware decided to disable The SSLv3 support for ESXi 6.0 by default for all services and ports.
This can be fixed by manually editing/etc/sfcb/sfcb.cfg and /etc/vmware/config
Or request veeam V8 update 3 patch from Veeam:
Request patch via support ticket: VeeamBackup&Replication_188.8.131.524_Update3
After enabling SSLv3 on the esxi hosts backups run as they did before the update to 6.0 Update 1.
Or install the patch to leave SSLv3 disabled but get Veaam working.
