Troubleshooting: Your Storage Array Software

SMrepassist -f E:

NOTE:

In Windows, the mount point path is a drive letter.

An error message is displayed in the command line when the utility cannot

distinguish between the following:

• Source virtual disk and snapshot virtual disk (for example, if the snapshot

virtual disk is removed).

• Standard virtual disk and virtual disk copy (for example, if the virtual disk

copy is removed).

Unidentified Devices

An unidentified node or device occurs when MDSM cannot access a new

storage array. Causes for this error include network connection problems, the

storage array is turned off, or the storage array does not exist.

NOTE:

Before beginning any recovery procedure, ensure that the host context

agent software is installed and running. If you host is started before it is connected

to the storage array, the host context agent software is not able to find the storage

array. If so, ensure that the connections are tight, and restart the host context agent

software.

• If a storage array is managed by using both out-of-band management and

in-band management using the same host, a management network

connection problem may prevent direct communication with the storage

array. However, you may still be able to manage the storage array over the

in-band connections. The opposite situation can also occur.

• If a storage array is managed through more than one host, it is possible

that the storage array may become unresponsive to communication over

the connections given by one host. However, you may still be able to

manage the storage array over the connections provided by another host.

Recovering From an Unidentified Storage Array

1 Ensure that the network connection to the storage management station

is operating.

2 Ensure that the controllers are installed and that the power is turned on to

the storage array. Correct any existing problems before continuing.
