LUN Mapping
After creating a logical drive (LD) or logical volume (LV), you can map it as is to a host LUN; or, if
partitions are set, you can map each partition to a specific host LUN. Altos RAIDWatch supports 32
LUNs per host channel (numbered 0 - 31), each of which appears as a single drive letter to the host
if mapped to a LD, LV, or a partition of either. Existing host LUN mappings can also be deleted. In
cases where certain mappings are found to be useless, or disk array reconfiguration is needed, you
can delete unwanted mappings in your system. This chapter explains the following LUN Mapping
features.
• Accessing the LUN Map Table, 9.1 on page 121
• LUN Mapping, 9.2 on page 123
• Extended LUN Mapping, 9.3 on page 129
9.1 Accessing the LUN Map Table
When you want to either create or delete a LUN Mapping or an extended LUN mapping, it is
necessary to access the LUN Map Table. The LUN Map Table lists the LDs, LVs and partitions that
have previously been mapped. To access the LUN Map Table please follow these steps:
1
In the Navigation Panel under Physical View, click on the Host Channel where you would like to
map a drive or volume (see Figure 9–1).
