When the UltraPath is not installed on a host, perform the following operations to query the mapping between host disks and LUNs.
Querying the Mapping Between Host Disks and LUNs (Solaris)
Step 1 On the storage system, obtain the host ID.
1. Log in to the command-line interface (CLI) of the storage system as a super administrator.
2. Run show initiator initiator_type=? [ wwn=? | iscsi_iqn_name=? ] to show the host corresponding to the WWN or iSCSI IQN.
admin:/>show initiator initiator_type=FC wwn=XXXXXXXXXXXXXX
WWN : XXXXXXXXXXXXXX
Running Status : Online
Free : Yes
Alias : suse2_01
Host ID : 2
Multipath Type : Default
The value of Host ID is the ID of a host corresponding to the WWN.
Step 2 On the host, obtain the host LUN ID corresponding to a disk.
1. Run the cfgadm -al and devfsadm -C command to scan the disk.
2. Run the echo | format command to update the number of devices and query the host LUN ID.
Step 3 On DeviceManager, view the host LUN ID of the LUN mapped to the host.
1. Log in to DeviceManager.
2. Choose Hosts > Hosts.
3. Choose the host queried in Step 2.2, and view the host LUN ID of the LUN mapped to the host.
Step 4 Check whether the two host LUN IDs are the same. If they are the same, the LUN is the one corresponding to the host disk.
