Automated system recovery
Problem
Network problems during ASR
Network problems can be the cause of different problems during ASR.
For example, the target system has two network adapters installed and one of them
had been disabled when the disaster recovery backup was performed. During ASR,
all devices are enabled by default. If both network adapters are active on the target
system during ASR, the network may not be configured properly, resulting in problems
connecting to the Cell Manager and Media Agent client. In this case, Data Protector
will switch to offline or local recovery, display a connection error or ASR will fail.
Action
To resolve the error, follow the normal ASR recovery procedure and press F8 when
the following text is displayed in the Disaster Recovery wizard:
Press F8 in the next 5 seconds to skip network
configuration...
This will revert from Data Protector ASR network configuration to the standard
Microsoft ASR network configuration.
Problem
ASR aborts if network card drivers are not present
This problem occurs during ASR on newer machines, for which no appropriate
network adapter driver is found on the Windows installation CD. When omnidr
attempts to configure the use of static IP addresses, it fails because network adapters
are not properly installed:
[Major] Failed to recreate the original network (TCP/IP)
configuration. Verify that the network adapters are properly
installed and working.
Action
• Install the appropriate network drivers before starting omnidr or if possible, use
a newer/slipstreamed version of the Windows installation CD that already includes
the required network drivers.
