Changes from IBM SmartCloud VSR, 2.0 to 2.1

Changes to VSR from VSR 2.0 to 2.1 are described in the following categories:

v “Major Core System Features and Changes”

v “User Interface Features”

v “Software Bug Fixes”

Major Core System Features and Changes

1. The AIX interface has been significantly improved as follows:

v DR Testing/Live Recovery can now automatically create an LPAR for itself.

Restriction: VSR customers must not name their LPARs using all of the

characters allowed. If this is the case, VSR cannot append the DR_ prefix and

any other necessary suffixes to that name. To avoid this, customers MUST

assign DR Lpar names with a length that allows VSR to add the DR_ prefix

and any other necessary suffixes without exceeding the LPAR naming

limitation.

v AIX Failback is now supported.

v User interface when dealing with AIX servers has been improved.

2. The Linux interface has been significantly improved as follows:

v Linux without LVM is now fully supported.

v New disks or Logical Volumes can now be added to an existing server.

v Resizes of valid disks (not members of the root Volume Group) are now

detected and handled automatically by VSR in the same way as Windows.

v The Protect Process method has been improved to alleviate duplicate PVs on

a Linux Replication Server (the root cause of many observed Linux issues).

User Interface Features

v User interface for reset password changed/improved to prevent identity

impersonation using a Secret question mechanic.

v Object Information page (right of tree view) now looks better for a Site and

contains commonly wanted statistics for the Site.

Software Bug Fixes

v System snapshots did not include the replication status of RedHat 6 and SUSE

servers. Fixed.

v When resetting a password, it got reset even if we could not send the email,

essentially locking the account. Now, we send the email first and only change

the password if we can send the email successfully.

v Calculations for determining the size of a System Reserve drive used to round to

the nearest known value (i.e. 99 and 101 rounded to 100). This can cause issues

with systems that have been upgraded rather than fresh installed. Rounding

removed.
