Virtual TapeServer 8.3 Release Notes
Known Issues | 45
 SSH login fails during Autocopy or Instant DR if replication has been setup. The 
reverse is true, too; SSH login fails during replication if Autocopy or Instant DR is setup. 
(TL-7003) 
WORKAROUND: Delete the entries from the known_hosts file and then setup SSH 
again.
 Replication jobs fail to run if a source has been removed from a target 
configuration. The error message will be similar to the following. (TL-6646)
“/DATA01/d00001-01-01-AS400/CMP178 : Received nil reply from location 
request for '/DATA01/d00001-01-01-AS400/CMP178' “
 Instant DR job remains running when an SSH connection has not been 
established to the target system. When initiating a Instant DR job and the SSH 
connection has not yet been established between VTS servers, the job never ends and 
stays in a “Running” state. (TL-6832)
 Communication with remote host fails if ICMP is blocked. Remote hosts used for 
Data Encryption backups, remote export, Instant DR, and AutoCopy attempt to ping the 
backup server name. If ICMP is blocked, adding the backup host fails even if SCP is 
configured and functioning properly. (TL-4371, EAR-6359)
 Replicate job to missing or remounted data location gives vague error message. 
If a data location is remounted to an alternate mount point or removed, the error message 
from a replicate job that should use this location does not indicate the cause. Note that 
after a data partition has been used, it is not supported to remove it nor to change its 
mount point. (TL-5859)
 Status of replication job that failed due to an error is displayed as cancelled. 
When an error is detected in a replication export or import job that causes the job to be 
terminated because the “stop on error” flag has been set, the job's overall status will show 
as “cancelled”. (TL-5862)
WORKAROUND: Check the job status details to determine the actual reason why the 
job ended.
 Re-replication of virtual tape is possible but cannot be restored. A virtual tape 
can be replicated from a source to a target, and from that target to a third VTS system. 
However, these “re-replicated” tapes cannot be restored. The restoration job can be 
created but will fail if executed. (TL-5892)
 Email notifications are not sent on the replication target system for replicate 
job completion. Replicate job completion is logged in the job log. (TL-5177)
 Replication lock files left on destination system. In the event of a prolonged network 
outage that occurs while a replicate job is in progress, lock files may be left on the 
destination (target) system. These lock files will prevent subsequent replications from 
completing on the locked cartridges. The condition can be diagnosed by viewing the log 
files on the source and destination systems. Contact technical support for instructions on 
how to clear these locks. (TL-5976)
 Replication locks and temporary files left behind after destination system 
failure. In some circumstances such as a system crash, lock files may be left in the data 
partitions and will prevent replication of the locked files. Contact technical support for 
assistance to clear the locked files. (TL-5944)
