Validation might fail without proper notification. Restart the HpRmCli Sql agent service on the
backup and production servers.
Problem:
A restore of a backup, which was created using Symantec NetBackup via the Recovery Manager
GUI, fails.
Suggestion:
When you use the Recovery Manager GUI to back up a virtual copy using Symantec NetBackup
and a directory is specified for backup, you must enter the directory name and path precisely,
including the upper- and lower casing (for example, MuTenFF). If the names do not match exactly,
a restore of this backup will fail as Symantec NetBackup is case-sensitive.
When backing up a directory, specify the directory in exactly the same case as it exists on the file
system.
Problem:
When you create a virtual copy on a SAN boot disk, the virtual copy creation fails with error
“Error-VSS_E_HOLD_WRITES_TIMEOUT.” The in-box system writer that enumerates all operating
system and driver binaries is included as well. The error usually occurs because the I/O cannot
hold the system writer.
Suggestion:
HP does not recommend placing a database on the SAN boot disk. Place all important databases
on separate SAN disks.
Problem:
As data blocks are copied per the copy-on-write technology, the space for virtual copies on the
virtual volume might become 100% full either if virtual copy space was statistically allocated as a
percentage of the virtual volume, or if there is no additional space available for the CPG to
auto-grow. If the space for virtual copies on a virtual volume becomes 100% full, the virtual copies
on the virtual volume may become invalid and subject to the Recovery Manager policy.
Suggestion:
Allocate more virtual copy space when creating virtual volumes during base volume creation, or
use CPGs to manage the data generated by copy-on-write technology.
Problem:
You just installed Recovery Manager, but all GUI and CLI commands fail.
Suggestion:
If you install Recovery Manager via a remote desktop session, the newly added environment
variables do not go into effect until you log out of the session. (If Recovery Manager is installed
directly from the system console, these variables should be available immediately.)
Problem:
Symantec NetBackup takes a substantial amount of time to complete a backup process.
Suggestion:
Make sure you have the latest maintenance package installed for your NetBackup application.
Problem:
Recovery Manager is running in a Windows cluster environment and the application event log
displays the Volume Shadow Copy Service error: “Unexpected error querying for the
IVssWriterCallback interface. Access is denied.”
Suggestion:
Reconfigure the security settings for the cluster environment as follows:
1.

Ensure that Failover Cluster MS DTC is installed. Failover Cluster MS DTC is required for the
following procedure.

2.

Click Start

→Run→dcomcnfg or Start→Administrative Tools→Component Services.

3.

Expand Component Services and click Computers.

4.

Right-click My Computer and select Properties.
