Enabled Software on Only One Host
New users sometimes forget to issue the sndradm -e enable command on both the
primary host and the secondary host. Other problems include making a mistake
when typing a disk or volume name or attempting to get access to a disk that does
not allow access.
Volumes Are Inaccessible
Verify that a volume or disk is accessible:
■ Confirm each volume is available on the primary and secondary host by using the
dd(1M) command to read a volume. Issue the following command on the primary
and secondary hosts for each primary, secondary, and bitmap volume:
The result shows that the command was able to read 10 512-byte records,
indicating that the volume is accessible.
■ Issue a newfs -N command and see if an error results. This command displays
file system information and does not display an error if the disk or volume is
accessible.
Note – Be sure to enter these commands properly, including the correct options.
Neither of these commands, if properly entered, overwrites data.
