Installation and Configuration
Installing additional Unisphere/Navisphere Host Agent software
The Unisphere/Navisphere Host Agent should be used to
automatically register host connections with the array. PowerPath
®
and ATF require different registration types and the
Unisphere/Navisphere Host Agent is the preferred method over
manual registrations.
You should install the Unisphere/Navisphere Host Agent software to
ensure the adapter connections are all registered correctly. For
instructions on how to perform this operation refer to the EMC
ControlCenter
®
Unisphere/Navisphere Host Agent software
documentation for your array type.
After the host agent has started and registered the new adapter paths,
you should refresh the host connections in the storage group to
ensure all available paths are assigned. To do this, you have two
options, depending on whether you want to disrupt the connectivity
of the host, as described next.
Option 1: Without disrupting host connectivity (more complex
procedure using Navisphere CLI):
Note: You must have Navisphere CLI installed. Refer to product notes for
complete usage instructions.
1. Using a command prompt, browse to the Navisphere CLI
directory (typically C:\Program Files\EMC\Navisphere CLI>.
2. Enter command
navicli -h <sp_IP> storagegroup
-connecthost -host <
hostname > -gname
<storagegroupname>
where <sp_IP> is the IP address of either array SP; <hostname> is
the hostname of the host connection to update and
<storagegroupname> is the name of the storage group of the host
connection to update.
3. When prompted, verify the <hostname> and <storagegroupname>
are correct as follows:
Connect host < hostname> to storage group
<
storagegroupname> (y/n)?"
Enter y to proceed.
