Step 4 Write some data to the file system.
The following example shows how to write some data to the file system:
host1# dd if=/dev/zero of=/mnt/dd.test count=1000
1000+0 records in
1000+0 records out
host1# ls -l /mnt/dd.test
-rw-r--r-- 1 root root 512000 Jul 25 13:25 /mnt/dd.test
Verifying with Element Manager
To verify that your host connects successfully to Fibre Channel storage, perform the following steps:
Step 1 Launch Element Manager and log in to the SFS that connects your SRP host to Fibre Channel storage.
Step 2 From the FibreChannel menu, choose Storage Manager. The Storage Manager window opens.
Step 3 Expand the SRP hosts folder in the Storage navigation tree. A list of SRP hosts appears. Those SRP hosts
that are successfully connected to storage appear as blue icons.
Step 4 (Optional) Verify LUN access with the following steps:
a. Click an SRP host in the Storage navigation tree.
b. Click the LUN Access tab in the right-hand frame of the display.
c. Expand all icons in the Accessible LUNs field. Those SRP hosts that are successfully connected to
LUNs appear as blue LUN icons.
