Simultaneous hotadd backups (from the same VMware backup host) fail with status 13
During simultaneous backups from the same VMware backup host, some of the backups may fail with status 13, "file read failed." A hotadd backup of multiple disks may take more time than the client-read timeout allows (the default is 300 seconds). The delay may be caused by locking timeouts in the VMware VDDK.
In the NetBackup Activity Monitor, the detailed status log may include messages similar to the following:
12/05/2014 06:43:53 - begin writing 12/05/2014 06:48:53 - Error bpbrm (pid=2605) socket read failed: errno = 62 - Timer expired 12/05/2014 06:48:55 - Error bptm (pid=2654) media manager terminated by parent process
The /NetBackup/logs/vxms log may include repeated instances of a VDDK message similar to the following:
12/08/2014 05:11:35 : g_vixInterfaceLogger:libvix.cpp:1844 <DEBUG> : [VFM_ESINFO] 2014-12-08T05:11:35.146-06:00 [7F1B1163F700 info Libs'] FILE: FileLockWaitForPossession timeout on '/var/log/vmware/hotAddLock. dat.lck/M34709.lck' due to a local process '15882-26732358(bpbkarv)'
To prevent this issue, do one of the following:
Reduce the number of hotadd backups that run simultaneously.
Increase the client-read timeout on the media server as appropriate (15 minutes or more):
In the NetBackup Administration Console, click Double-click on media server .
