56 Identifying disk and array LUN information in command output
Identifying disk and array LUN information in command output
Format of disk and
array LUN
addressing Information about native disks and array LUNs is shown in output from some
Data ONTAP commands—for example, in the output from the
storage show
disk
command. The format of the “disk addressing” is different, depending on
whether the information shown is an array LUN or a native disk.
Format for disk names: Names of disks on native disk shelves are in the
following format: HA . disk_id .
HA represents to the host adapter number, which is the slot number on the
gateway to which the host adapter is attached, as shown in the following
examples:
◆
0a—for a disk shelf attached to an onboard Fibre Channel port
◆
7a—for a shelf attached to the A port of a host adapter installed in slot 7
Example:
0a.16
Format for array LUNs: Array LUN name format is as follows.
Direct-attached configuration Fabric-attached configuration
For Data ONTAP 8.0 7-Mode and
7.x releases:
adapter . id.lun-id
adapter is the host adapter number
on the gateway.
id is the adapter port on the storage
array.
lun-id is the full LUN ID.
For Data ONTAP 8.0 7-Mode and 7.x
releases:
switch-name : port . id . lun-id
switch-name is the name of the switch.
port is the switch port.
id is the device ID.
lun-id is the LUN ID.
Example:
s2:4.126l4
or
s2:4.127l4
(depending on the type of switch)
