path environment. Use the following procedure to configure the environment
in Figure 3-30 Device Configuration When a Logical Volume on a SCSI Device
Is Moved to an HDLM Device on page 3-202 .
Figure 3-30 Device Configuration When a Logical Volume on a SCSI Device
Is Moved to an HDLM Device
In Figure 3-30 Device Configuration When a Logical Volume on a SCSI Device
Is Moved to an HDLM Device on page 3-202 , sdn indicates the different LUs.
sddlmad1 and sddlmad2 indicate the HDLM devices corresponding to each LU.
To move the logical volume to an HDLM device:
1
.
Make sure that HDLM has been installed.
Execute the rpm command to make sure that HDLM has been installed.
