DAC960 Disk Array
DAC Utilities for Banyan Vines
Included in this diskette are the Utilities for Banyan Vines for EISA and PCI
DAC960s. The EISA DAC960 drivers for Banyan Vines are packaged by Banyan Systems in
many of their releases. Updated drivers which also support PCI DAC960's are
provided by Mylex.
This set of utilities allows a system administrator to manage
DAC960 disk array systems installed on Banyan Vines servers from
any workstation in the network. The disk array on any of the servers
can be managed from the workstation.
Installation :
The following files can be found in the BANUTILS subdirectory of
Software Kit 1.04.
For description purposes, they can be separated into two
sets as follows:
SET #1:
README.DOC (this file)
INSTALL.EXE
INST.DB
REMOVE.EXE (used to remove the service)
SERVICE\INSTALL.INI
SERVICE\INSTALL.SCR
SERVICE\FILE1.0
SERVICE\FILE2.0
SERVICE\FILE3.0
SERVICE\FILE4.0
SERVICE\FILE5.0
SET #2:
ADDUSER.EXE
DELUSER.EXE
LISTUSER.EXE
DACADM.EXE
Note that the examples given in this document assume a floppy
drive A:, and a shared logical drive E:. It is assumed here that
DAC960 controller is installed and functioning as a primary
controller on the server.
The installation procedure involves copying the required utility
files, installing the DAC960 "ioctlsrv" service on the Banyan
Server, and adding/starting the ioctl service on this server.
1. Login as administrator to the server from a workstation.
2. Insert the DAC960 Vines utility diskette into a floppy drive
and change to the BANUTILS subdirectory on that drive.
Then type "install <servername>" as in the following example:
E:\> a:
A:\> cd banutils
A:\BANUTILS\> install <servername>
(where "servername" is the server on which you
want to install this "ioctlsrv" service.)
3. At the following message prompt, type y for yes:
Do you really want to install the dac960 ioctl
service? (y/n) y
Then the screen will display some messages showing that the
ioctl service is being installed.
NOTE: Before running mservice, Services must be Stopped and Restarted
4. Change drive to E:. At E: prompt, invoke the Banyan utility
"mservice" as shown in the following example.
A:\BANUTILS\> e:
E:\> mservice
5. Select "Add a server based service" from the mservice menu.
Then enter the StreetTalk name and description of the service
as prompted. The StreetTalk name for this service should be
"ioctlsrv@servername@servers", where servername is the name
of your server.
6. Select "Disk Array ioctl service" from the list of services
displayed. Select the disk (e.g. disk1) on which the service
will reside. Hit F10 at the "Service Configuration" screen.
7. When prompted, select "Yes" to start the service immediately.
8. Make sure the ioctlsrv service is running from the service
monitor screen on your server console.
9. Copy the following files to the server. Note, these utilities
need to be accessed only by an administrator.
ADDUSER.EXE
DELUSER.EXE
LISTUSER.EXE
DACADM.EXE
This completes the DAC960 Vines Utility Installation.
Removing the IOCTL Service :
Follow the Banyan documentation to STOP a service, and then
DELETE it through MSERVICE.
Then from the workstation use the REMOVE.EXE utility included
in the utility diskette to delete the previous "ioctlsrv" files.
Type the following:
remove <servername>
Bugs and Known Limitations:
DACADM utility will not work on a workstation with Monochrome
monitor.
Description of Utilities :
1. DACADM.EXE
dacadm <servername>
This is the main disk array administration utility. For more
details about this utility see the section on DACADM utility
below.
2. ADDUSER.EXE
adduser <servername> <user streettalk name>
This utility will add a user to the list of users who will receive
a single line administrative message from the server. This message
will inform the recipient of any abnormal condition on a server
having the disk array system.
3. DELUSER.EXE
deluser <servername> <user streettalk name>
This utility will delete a user from the list of users who will
receive a single line administrative message from a server having
the disk array system.
4. LISTUSER.EXE
listuser <servername>
This utility will list all users who will receive a single line
administrative message from a server having the disk array system.
DACADM Utility :
This is an administrative utility for the DAC960. This utility will
be run on a workstation on the Banyan Vines network. Once invoked,
it comes up with a main menu screen similar to the one shown below.

Fig 1.0 : Disk Array Monitor (Main Menu)
Main Menu :
The top portion of the screen lists the 5 main options namely Select
DAC, Standby, Rebuild, Chng Dev and Quit.
The rectangular box below this displays details about the option
currently selected.
Below that a matrix of drives connected on various channels of the
selected adapters are displayed. The left most column corresponds
to SCSI ID 0 and SCSI ID is incremented for every column. The
letters ONL, STB, DDD and --- are displayed for an Online,
Standby, Dead and Not Present disk drive respectively.
On the right of the drive matrix, a System drive table is displayed.
This indicates the status of the System drives as ONLN, CRIT, OFLN
for Online, Critical and Offline System drives respectively.
Below this is the message log box, where the description about
the drive failures, status of standby or manual rebuilds etc.
are displayed for the selected adapter. This information is
also appended into a file by name "dac960.log" on the server.
The last line displays the number of the currently selected DAC960.
Use the left and right arrow keys to select one of the five options
displayed on top of the screen. The selected option box is
highlighted and also the box below the option box displays a
brief description about the option. Hit the ENTER key to select the
highlighted option.
Select DAC :
Once the Select DAC option is selected, a window pops up displaying
the possible four DAC960s. Use the arrow keys to highlight the
appropriate DAC960 that needs to be administered and hit Enter key
to select it. The arrow keys can be used to select only a DAC960
controller present in the system. The main menu is displayed now and
the currently selected DAC960's number is displayed on the last line
of the main menu.
Standby :
This option is used to make a drive (that is not currently configured
in any pack) standby. Once this option is selected, the cursor jumps
to the drive matrix area and allows the selection of the drive ( to
be made standby ) using the arrow keys. Select a drive and hit Enter
to make the selected drive standby. The controller will try to start
the drive and on successful starting of the drive will make the drive
a standby drive. Note, only disk drives that are not part of any pack
can be made standby drives. Hit Escape key to return to main menu.
Rebuild :
This option is used to rebuild a drive that was killed ( shown as
DDD on the matrix area ) by the DAC960. Before this option is
invoked, the killed drive has to be replaced by a properly working
drive. Once this option is selected, the cursor jumps to the drive
matrix area and allows the selection of the drive (to be rebuild)
using the arrow keys. Select a "DDD" drive to be rebuild and hit
Enter to start the rebuild. The selected drive is then started
and rebuild. While the rebuild is going on, the Rebuild status is
displayed on a horizontal bar for every system drive that needs to
be rebuild. Also the progress and completion status of the rebuild is
indicated in the message log area of the main menu. On successful
completion of a Rebuild, the drive is made Online and indicated in
the matrix by words ONL. If the Rebuild process is not successful, a
"Rebuild Error" message is printed on the screen.
Chng Dev :
This option is used to quiet a SCSI channel on the DAC960, so
that the dead drive on that SCSI channel can be replaced online
for rebuilding. Once this option is selected, the cursor jumps
to the matrix area and allows the selection of channel to be
stopped using the arrow keys. Select a channel (where the
dead drive needs to be replaced ) and hit Enter to stop the
activities on the channel. At this point of time disconnect the
power cable to the dead drive and disconnect the SCSI cable on
the dead drive. Plug in a new good drive with the same SCSI ID,
connect the SCSI cable and power cable to it. Press a key to
resume the channel activities.
Note : The channel activities will automatically be restarted in
about 30 seconds of stopping the channel (without updating the
screen). Hence the drive removal and replacement needs to be
done in less than 30 seconds. The removal and replacement can also
be done in two stages, stopping the channel before removal and
replacement.
Quit :
This option is used to terminate the program.
