:
:
/dev/sddlmaa1 on /boot type ext2 (rw)
/dev/sddlmaa4 on /tmp type ext2 (rw)
/dev/sddlmaa5 on /var type ext2 (rw)

3.7.4 Upgrade Installation in an Environment Where an HDLM
Device Is Used as a Boot Disk
This subsection explains how to perform an upgrade installation of HDLM and specify
environment settings in a multi-path configuration boot disk environment using the
HDLM device.
Note that if settings are incorrect, the OS might not start. For details about what action
to take if the OS cannot be started from an HDLM device, see 3.7.7 Countermeasures
