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.

# dd if=volume-name of=/dev/null count=10
