Q: What is SSL?

A:

SSL stands for Secure Sockets Layer, which is a protocol developed by Netscape for transmitting private documents through the Internet. SSL works by using a private key and public key to encrypt and decrypt data that's transferred over the SSL connection for the purpose of secure trusted authentication. Both Netscape Navigator and Internet Explorer support SSL, and many Web sites use the protocol to obtain confidential user information, such as credit card numbers. By convention, Web pages that require an SSL connection start with https instead of http.

Q: Why can't I see the drive letter assigned to the drive on my Windows 2000 host?

A:

If you have assigned a drive letter to your disk and you do not see the drive letter under the mount point column of the drive, then the drive is probably a dynamic drive. Command View currently does not support dynamic disks. However, you will still see most of the information about the drive except the drive letter assigned to the drive.

Back to Questions about Path Connectivity

Q: Are there any firewall issues associated with the Host Agent?

A:

No.
In this release, if the hosts are within the management station's firewall/subnet and/or you are using the Remote Deployment tool to deploy the Host Agent, the Regular Host Collection will discover the hosts.

If you did not use the remote deployment tool to install the Host Agent AND the host is not in the same firewall/subnet as the management station, please use the Path Connectivity Administration > Host Discovery > Host Mgmt to add the host into the Path Connectivity.

Once the hosts are in the Path Connectivity, they will be discovered during the Regular Host Collection.

Back to Questions about Command View XP Host Agent

Q: My host has multiple network cards. Will this cause any problems with the Host Agent?

A:

To avoid any host discovery problems, you should make sure that the primary network card has the IP address that you want to connect from the Management Station.

For local installation, the installation script will not select the communication IP address for the host (remote installation will do that).

To select your communication IP address for local installation, please do the following. (Assuming a default installation directory)

1. Open c:\sanmgr\hostagent\config\commIpAddr.txt file (Windows host).
2. Open /opt/sanmgr/hostagent/config/commIpAddr.txt file (UNIX host).
3. Enter the IP address that the host is using for communicating to the Management Server.
   The commIpAddr.txt can only have one IP address.
4. Stop and start the hostagent software.

In a Windows host:

net stop hostagent
net start hostagent

In a UNIX host:

cd /opt/sanmgr/hostagent/sbin
./HA_trigger stop
./HA_trigger start
