HP 3PAR Recovery Manager Software - Manual (Page 100)

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.
5. Select the COM Security tab.
6. Under Access Permissions, click Edit Default.
7. Add a Cluster Service account and select Local Access and Remote Access.
8. Reboot the machine.
9. Perform these steps on the second node.
Problem:
You attempt to perform a media restore using the Recovery Manager CLI -ts command and the
attempt fails.
Suggestion:
If the restore log contains the error message: “client <client> peer name <peer name> is
invalid for restore request,” the restore client is different from the backup client. Configure Symantec
NetBackup to perform a redirected media restore as follows:
