Address access control concerns
to ensure users and
applications can still access their data after the migration
|
The most obvious and embarrassing way to
find that your SFS migration has failed is to arrive in the office on
Monday and find that your users cannot find or access their data
anymore. You need to identify all users and applications that access
each minidisk to be migrated so that you can ensure that the appropriate
SFS authorizations are provided. |
|
Identify applications that will require
modification
to be able to access information in SFS |
Applications will need to be modified to
take advantage of SFS. Generally, most applications use a LINK and
ACCESS command to access information on a minidisk. With SFS, only an
ACCESS command is required. The complete list of VM commands that
affect applications is: |
|
LINK, ACCESS, DETACH, QUERY LINKS, QUERY
V device,
QUERY DISK, LISTFILE, & RELEASE |
|
Every application needs to be examined for
instances of these commands. You need to examine all system and user
applications. Many VM users write "EXECs" that contain these commands.
Locating and modifying these user EXECs is very time consuming and
expensive. |
|
Update applications to enable them to access
information in SFS
|
Applications must be updated to address
these changed commands and responses. Each application identified in
the previous step (both system and user applications) must be updated
to work with SFS instead of with minidisks. These changes must be
synchronized with the migration of data used by users and
applications. |
|
Test system with SFS data
|
All applications and procedures must be
tested to verify that they function correctly with SFS and to ensure
that nothing was overlooked when identifying the required changes.
User procedures may vary from user to user. Many migrations fail to
test each user's procedures. |
|
Train users on new commands and look and feel of SFS
|
Your users will be affected by the changes
that occur when using SFS. While all of the commands identified above
are a concern, the following are the most commonly used commands:
|
|
LINK and ACCESS, QUERY DISK, & RELEASE
(DETACH |

SafeAccess identifies minidisks that are good candidates for migration
to SFS |
|
SafeAccess converts existing access controls to SFS or SafeSFS rules.
|
|
SafeAccess identifies applications and users that are affected by SFS migration. |
|
SafeAccess eliminates the need to update your applications.
|
|
SafeAccess eliminates the requirement to train users. |
|
SafeAccess eliminates the need to perform costly, exhaustive tests.
|
|
You simply monitor the migration process
and add newly freed space to SFS as necessary.
|
|
A Complete
SFS Migration Solution |
|
Identify Minidisks to Migrate
|
SafeAccess evaluates your system and tells you which minidisks can
be migrated to SFS and which ones should be migrated first. You simply
guide the process. |
|
Determine Existing Access Control and Implement
Comparable Controls in SFS
|
SafeAccess determines your existing minidisk access controls and produces
SafeSFS or SFS rules that enable users and applications to continue to
access information without costly or embarrassing outages. |
|
Identify Applications That Require Modifications
For SFS |
SafeAccess evaluates your system and identifies applications that will
require modifications to take advantage of SFS. SafeAccess provides you
with a list of both users and applications that are using each minidisk
on your system. |
|
Update Applications That Require Modifications
For SFS |
SafeAccess dynamically enables your applications to use the new SFS
interfaces for accessing information in SFS. SafeAccess does not
modify your applications. All applications continue to work just as they
did when information was located on minidisks. |
|
SafeAccess dynamically enables your users to use existing minidisk
interfaces. This eliminates the need for user training because your users
continue to LINK, ACCESS, QUERY, etc. just as they always have with minidisks. |
|
SafeAccess
Pays for Itself! |
|
Installing and using SafeAccess is substantially cheaper than addressing
all of the SFS migration issues. VM installations currently spend months
or years attempting to address SFS migration concerns and the costs run
into the hundreds of thousands of dollars. SafeAccess eliminates these
costs and allows you to recognize the cost savings provided by SFS immediately!
SafeAccess and SafeSFS combine to provide you with a turnkey SFS migration,
implementation, security, and administration solution that enables you
to use SFS and substantially reduce your cost of computing on VM/ESA.
