Internal LUN, device recognized by the host
To verify the correspondence of the internal LU number in the array and the
device name recognized by the host, use the inqraid command tool or the
raidscan command. The following example illustrates using the inqraid
command tool in the HP-UX system.
•
Figure 2-7: Correspondence between Internal LU and Device
Recognized by Host
For details on the inqraid command tool, refer to Inqraid command tool, on
page 1-85 . For details on raidscan command, refer to Raidscan command,
on page 1-51 .
Pair-splitting guidelines
When the host cannot recognize an LU while the protection function is ON,
the following message is displayed and operations to the pair of the
unrecognized LU cannot be performed.
Figure 2-8: Message Displayed when Host Cannot Recognize an LU
Issue the pairdisplay command and verify the pair status. An example is
shown below.
•
Figure 2-9: Pair Status Verification
After the pair status is verified, turn the protection function OFF, restart
HORCM, and then split the pair (to turn the protection function OFF, delete
the environment variable $HORCMPROMOD). For details on the
environment variable, see Environment variables, on page 1-3 .
