 FIX    DATE     DESCRIPTION
====  =======   =======================================================
0      2/9/95   Sysback Version 3.2.1 Initial Availability

1      2/21/95  Cosmetic changes:
                a) LED "\< 0 >" appears if certain device code not 
                   installed when performing anetwork boot.  Changed to 
                   "0 0 0" for consistency.
                b) Listing available volume group backup image files 
                   from SMIT only listed /usr/lpp/sysback/images contents
                   even if user added other directories to the imagelist
                   file. Now lists images in any directory specified in
                   in imagelist file.

2      2/21/95  Client not setup correctly for network boot if client
                hostname also had aliases defined. Fix appled.
                WORKAROUND: Edit the /etc/bootptab file and remove the
                comma (,) which appears immediately after the client 
                IP address.
                
3      3/1/95   Syntax error in /usr/sbin/editvginfo program occurs if
                on AIX version 4 when striped logical volume exists in
                the volume group.

4      3/1/95   When creating full system backup from client to server,
                the following errors may occur:
                a) When creating full system backup on AIX Version 3,
                   error message displayed if \<8MB space available on 
                   local system when backing up to a server. The space 
                   checking should occur on server on AIX Verison 3.
                b) Warning message displayed indicating client and server
                   are not at same release level, although both were the
                   same.

5      3/1/95   Device Configuration was not recovered from original
                system when installing a client who was booted from a
                network install server and the network install server
                had never run a sysback full system backup.

6      3/2/95   getrootfs would not work when executed from a system
                booted from a network boot server.

7      3/7/95   Fix \#5 above causes mkboottape to fail because rda
                program is not found in /usr/lpp/sysback/inst dir.

8      3/7/95   Network boot failed at c28 LED when booting from 
                standard ethernet adapter on AIX 3.2 system.

9      3/7/95   Message "No install options available on the server"
                appeared when performing remote tape installation and
                multiple volume groups are to be installed.

10     3/23/95  Provided more detailed error message when number of 
                copies and logical partitions in device configuration
                database does not match actual physical partition map
                for a logical volume. Full system backup halts with this
                error to prevent erroneous re-creation of the LV.

11     3/23/95  Installing a system from tape with multiple volume 
                groups may create the VGs in different order than 
                VG data is restored, resulting in data restored for
                filesystems which had not yet been created.

                If this problem occurs, you can continue through
                install process and reboot in normal mode. Remove the
                offending volume groups and recreate and restore the
                volume group properly from the full system backup.

12     3/30/95  jfsrestore command fails on AIX Verison 4 with syntax 
                error due to -B flag being removed from restbyinode
                command in AIX.

                If necessary, customer can manually edit the jfsrestore
                command and remove -B flag from all occurrances of
                restbyinode command (do not remove on AIX V3 systems).

13     3/30/95  Errors when creating a bootable tape when backing up
                from an AIX V3 system to an AIX V4 system. Caused by
                inability to mount the /ethan (temporary) directory
                when executing remote process. Since the bootable image
                is not compatible with the backup anyway (warning 
                messages point this out), the process has changed so as
                not to create a boot image at all when backing up from
                AIX V3 to AIX V4 (and appropriate warning message is
                displayed). This is not a problem when backing up from 
                AIX V4 to AIX V3 or from same to same.
                
14    4/3/95    The prompt: "7) Inter-PV policy:" should read
                "6) Inter-PV policy:" when recreating a logical volume 
                or volume group on an installed system. This occurs only
                when the LANG variable is set to En_US. 

15    4/21/95   The prompt "7) Physical Volume list: (If specified,...)"
                should read "7) Physical Volumes:" when recreating a 
                logical volume or volume group on an installed system.
                This occurs only when the LANG variable is set to En_US.

16    4/21/95   getrootfs did not properly mount filesystems for 
                maintenance work after booting over the network from an 
                AIX Version 4 server.

17    4/21/95   When recreating a logical volume on an installed system,
                you were unable to change the number of copies on a
                3.2 system. Erroneous message indicated that you could
                not change stripe size on a striped logical volume.

18    4/21/95   When recreating a logical volume, either on an installed
                system, or during the installation process, multi-copy
                logical volumes would only be created with one copy if
                not enough disks were selected, even if user selected to
                allow multiple copies on a single disk.

19    4/25/95   When fowarding a single image which spans more than 2 
                volumes, received message "Backup header on /dev/rmt0.1 
                does not match previous volume". Also reduce time 
                between checking that new volume has been inserted.

20    4/26/95   1) Could not boot a client machine from a network boot
                server over a gateway. System LED stopped at 517. To
                prevent this, new options for entering gateway address
                and subnet mask added to mksbnetboot program and to
                SMIT options for configuring network boot client. 
                2) Removed hardware adapter address option as this
                is not needed to boot a standalone machine.
                3) Allow entry of "ethernet" or "token-ring" for creating
                network boot image and configuring network boot client, 
                even if adapter does not exist on the server. This allows 
                ethernet clients over a gateway to boot from a server on 
                a token-ring network and vice-versa.

21   5/8/95     Fix \#20 above produced the following error when executed
                against a token-ring adapter:
                "Invalid network device specified!"
                If encountered, edit /usr/sbin/mksbnetboot, and change
                line \#147 from "tr0" to "tok0".

22   5/8/95     Added a dummy password to the tapesvs user due to problems
                with rsh command at some levels. This user id does not
                allow login access, but rsh sometimes requires password
                be set anyway.
        
23    5/8/95    Changed permissions on /usr/lpp/sysback/images and
                /usr/lpp/sysback/bf directories to prevent users from
                removing eachothers backup image files. Users could never
                write over, but could remove others files.

24    5/11/95   Fix \#22 above did not work on all levels of rsh. Required
                encrypted password. This problem will prevent remote 
                backups from being performed with one of the following
                errors:
                        Permission Denied
                        Your encrypted password is invalid

25    5/24/95   Added support for 3480 & 3490 drives when attached to a
                channel adapter.

26    5/26/95   LV names larger than 14 characters caused errors when
                recreating volume groups or logical volumes. AIX allows
                LV names up to 15 characters. Changed to allow unlimited
                LV name size but only displays first 14 characters.

27    5/31/95   User recieves the message "Another boot image is currently 
                being created .. waiting ..". This message appears every
                15 seconds forever. This occurs only after the user
                typed CTRL-C when previously creating a tape boot image.
                To remedy the problem, type the following:
                mv /usr/lpp/bosinst/bi_main.sbsv /usr/lpp/bosinst/bi_main.

28    6/1/95    Hardcoded path for rsh command in all programs. This is
                needed on systems with kerberos installed so all Sysback 
                commands call AIX rsh and not kerberos rsh.

29    6/1/95    Added Network Hardware Address option back into the
                mksbnetboot command for configuring a network boot
                client. Usnig the H/W address allows client system to
                be booted from bootp screen without entering client 
                and server IP addresses as long as server and client
                are on the same local network (i.e. no routes).

30    6/12/95   List/Verify/Restore System Backup through SMIT
                fails with the following message if tape drive 
                is not set to block size of original backup: 

                    Unable to read the volume header on device /dev/rmt0.

                Since sysrestore is executed multiple times through 
                SMIT, there is no way to set the block size only once 
                to prevent rewinding the tape multiple times. If the 
                block size is not correct before attempting restore, an 
                error message is displayed, and user is required to set 
                the block size to the correct value and try again. This 
                is not required when running sysrestore command from the 
                command line.

31     9/8/95   Changes to AIX bosboot command cause creation of remote
                boot tape to fail when backing up from a 4.1.3 client.
                Messags is "dd: invalid parameter".

32    10/20/95  sbwrite command sometimes returned error "Invalid status
                received by process 0!" when writing to multiple copies
                using -C flag.

33    10/27/95  Buffering problem in lvrestore command caused restores 
                of raw logical volume data to take 2-4 times longer 
                than the original backup. Restore of raw data now 
                completes in approx same time as backup.
