You must complete the worksheet for all installations that include a management
console. Before you complete the worksheet, review the exceptions that are listed
in the notes at the bottom of the worksheet.
Remote support settings
The remote support worksheets specify whether you want outbound (call home) or
inbound (remote services) remote support, or both.
Ensure that you enable both outbound and inbound support to help you maintain
the highest availability of your data.
When you enable outbound (call home) remote support, your management console
sends an electronic call home record to IBM support when there is a problem
within the storage complex. If inbound remote service is also enabled, an technical
service representative can securely sign on to the management console from a
remote location in response to the service call.
The storage system uses secure Internet SSL connectivity for the outbound (call
home) remote support connection.
Assist On-Site (AOS) is available as a secure inbound remote service option. AOS
provides a mechanism to establish a secure network connection to IBM over the
internet by using SSL encryption. AOS can be installed on a customer gateway
server in a DMZ or, if your security guidelines allow, it can run directly on the
storage system.
In addition to AOS, you can also use 'rsc' (remote support center). It is a simple
SSH proxy based remote service solution which can be used if AOS does not meet
your security guidelines. Contact your technical service representative for more
information on RSC.
Remote code load (RCL) requires outbound (call home) remote support, and either
AOS or RSC.
The management console can also be configured to offload error logs to IBM over
the Internet by using FTP. This option is normally only used when the customer
does not want to send error logs over an encrypted connection.
For any of the remote support connectivity methods, you can use the data storage
command-line interface (DS CLI) and its audit log feature to review who
completed any remote service on your storage system, and at what time the work
was completed. Contact your technical service representative for more information
on which service actions are completed remotely. You can also use DS CLI to
control network and remote service access to each management console and the
storage system.
The IBM AOS Redbook at http://www.redbooks.ibm.com/abstracts/
redp4889.html?Open provides additional information on AOS as a secure remote
service solution.
