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. _________________Disk Array Monitor V 1.00________________________ | | | ______________ ___________ ___________ ____________ ________ | | | Select DAC | | Standby | | Rebuild | | Chng Dev | | Quit | | | |____________| |_________| |_________| |__________| |______| | | | | ___________________________________________ | | | | | | |_________________________________________| | | | | ----------- Target--------> ___System Drive___ | | | 0> ONLN RAID-7 | | | Ch-0> ONL --- ONL --- | 1> CRIT RAID-5 | | | | 2> CRIT RAID-1 | | | Ch-1> --- DDD --- --- | | | | | | | | Ch-2> --- --- STB --- | | | | | | | | Ch-3> --- --- --- --- |________________| | | | | Ch-4> --- --- --- ONL | | | | | | _______________<Message Log>____________________ | | | | | | | | | | | | | | |______________________________________________| | | | |________________________________________________________DAC #1__| 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.Download Driver Pack
