AIX to HP User Filesystem Migration Status

The filesystem migration was completed on Saturday morning, March 29,
with the following results:

o       All user filesystems were migrated off of the AIX cluster. This
        means:

        +       Your files are no longer located on your AIX
                home site, they are located on the HP-UX Service Guard
                Sites "polysrv1" and "polysrv2".

        +       You may new log into any of the AIX systems,
                except "oboe", while they remain in service.

        +       Some users may notice they have different home
                sites than before the migration.

        +       Your login path has been changed to reflect the
                new path to the combined filesystems on the HP-UX
                servers.

        +       All Access Control Lists on the migrated user
                filesystems no longer exist and cannot be recreated
                (they are not supported under HP-UX 10.x with NFS).

        +       All users were migrated with the default quotas
                for their group if they had a default quota prior to the
                migration.

                NOTE: The "/ulib" and "/u22" filesystems have
                not been migrated yet. They are still located on their
                respective AIX sites "flute" and "oboe". They will be
                migrated at a later date to systems which are
                appropriate to their use.

o       Quota Problems: Users who had extended quotas were transferred
        with a zero quota and are to be reset manually. During the
        manual quota setting process, the quota checking function was on
        unknown to the systems admins performing the quota settings.
        This was due to a bug in the command that turns quotas off. As a
        result, all users who had not yet had their quotas set after the
        quota function started, will have lost the contents of any files
        that were written during this time period.

        If your account had its quota set incorrectly, and you logged in
        on Saturday through Monday at 9:30 AM and edited any of your
        files, you will have lost the contents of these files. This
        includes mail folders, saved files, program resource control
        files (.pinerc), edited files, etc..

        Also, any mail that would have been passed through a mail
        "filter" (the elm mail filter) and saved within the account
        would have been lost or bounced back to the sender with an
        obscure message. This again is a fall out of the quota problem.

        NOTE: If you experienced a loss of data due to the quota problem
        and wish to recover the file(s), please come to the Help Desk
        office in CSc 14-114 and complete the File Recovery Form. The
        corrupted files will be restored as soon as possible.

o       NFS Mounts became unstable shortly after the migration crew had
        finished their efforts on Saturday. This resulted in the Service
        Guard™ packages "polysrv1" and "polysrv2" failing over multiple
        times to their respective secondary machines. As of noon on
        March 31, 1997, this seems to have been brought under control.

        Mail received during periods of NFS instability that would
        normally have been forwarded on or filtered was delivered into
        the user's incoming mail folder (INBOX) instead.

ITS staff members are taking the following actions to remedy the
situations listed above:

o       Until HP fixes the quota command bug and we have set all user
        quotas to appropriate values based on their original AIX
        settings, quotas will remain turned off. Users are cautioned
        during this period to be aware of the amount of disk space they
        are using; once quotas are turned back on, users may find that
        they have exceeded their default quota. When quotas are turned
        back on, users will experience NFS error messages and possible
        corruption of files if they have exceeded their quotas.

o       The Service Guard™ fail-over of fileserver packages is being
        addressed with Hewlett-Packard. This seems to be a performance
        related issue on the system that the package is running on. We
        have moved the packages to the appropriate server platforms and
        feel that the situation has stabilized.

o       Lost files caused by the quota problems will be recovered for
        user by ITS. In order to have a file recovered, please come into
        the Help Desk in CSc 14-114 and fill out a File Recovery Request
        Form. The files will be restored as soon as possible.

ITS wishes to thank the users for their patience in this matter as we
continue the migration from AIX to HP-UX.
