TECHNICAL BULLETIN
Bulletin 1-254
Date: October 17, 1989
Operating System Updates Found in NetWare Version 2.15, Revision C
This bulletin explains some limitations experienced by users of NetWare
v2.15, revision A. If you have experienced any of the following
limitations, call 1 (800) UPDATE1. Be prepared to provide full details
of your system.
Operating System and External Bridge Routing Limitation
The NetWare v2.15 operating system and external bridges have a router
limitation. If eight or more file servers exist on an internetwork,
every eighth server in the router table could be lost. If users attempt
to log in to a fully functional file server, but some users receive the
message "Unknown fileserver," you may have this limitation.
Disk Mirroring Limitations
1) "ABEND: Invalid Redirection Index Table"
You may have received the error above after using the REMIRROR
command on a disk drive larger than 255MB. This has been
solved--you will only receive this error message when something
has actually happened to the Redirection Index table.
2) Previously, disk mirroring could not be used for disk drives greater
than 255MB if the first volume had been assigned less than the
default 255MB. In 2.15 revision C the installer is not limited
to the default volume size on large disk drives.
3) If disk mirroring is occurring on a single disk coprocessor, a
mirrored disk drive failure could take down the entire channel.
This problem has been fixed--when a mirrored disk drive failure
occurs, only the failed device is shut down. The rest of the
channel is not affected.
Removable Disk Drives
1) Directory caching on a removable hard disk drive can now be enabled
without causing a GPI.
2) The DISMOUNT command will now free the memory allocated by the
MOUNT command. (Previously, too many consecutive MOUNT and
DISMOUNT commands would eventually hang the server.)
3) Multiple removable drives can now be mounted correctly.
