Disk configuration terms and concepts
Logical disk configuration
Inode allocation
Disk ordering
Installing additional fixed disks

Note: Banyan server software is installed on /disk1 of your server and not on an additional file systems. Additional file systems and file systems on additional disks can contain Banyan services and the data areas used by those services, such as storage for a file service, but cannot contain the primary server software. Banyan recommends that you use /disk1 for Banyan software only and that you use other files systems (/disk2, /disk3, etc.) for services and data areas. If you follow this recommendation, /disk1 can be a minimum of 150 MB.

Inode Allocation

For disks with capacity up to 64 MB, one inode is allocated for every 1 KB of disk capacity.
For disks with capacity greater than 64 MB and less than 2 GB, 65,536 inodes are allocated for the first 64 MB and, for the disk capacity in excess of 64 MB, one inode is allocated for every 4 KB of disk capacity up to a maximum of 524,264 inodes.
For disks with capacity greater than 2 GB and less than 16 GB, 524,264 inodes are allocated for the first 2 GB and, for the disk capacity in excess of 2 GB, one inode is allocated for every 8 KB of disk capacity up to a maximum of 2,097,128 inodes.

I = B

I = 65536 + ( (B - 65536 ) / 4)

I = 524264 + ((B - 2097152) / 8)

Note: It is possible to run out of inodes before running out of file system space if all files are of a minimum size (say 1 KB).

Using Multiple Fixed Disk Controllers

Note: No third-party, monolithic disk drivers are presently available.

Example Three Controllers with VINES 6.x and VINES 7.00

Note: Some VINES 6.x drivers include the necessary support to allow any of the three controllers control the boot disk.

Installing Additional Fixed Disks

To Install an Additional Fixed Disk

1. If the additional disk is not already low-level formatted, format the disk using the format utility supplied by the system or controller manufacturer.

2. Install the disk in the server.

3. Boot the server and watch for this message:

Disk /dev/rdsk/Xs0 contains an inappropriate VINES file system.
Consult documentation for proper disk installation procedures.

=====================================================
NOTICE: Logical disk N needs to be added.
=====================================================

Use CTRL-S to stop the display and make note of the N. The logical disk number of the new disk is equal to N.

Use CTRL-Q to restart the display.

4. At the Operator Menu, select Shut Down Server Software. The system prompts you to confirm the shut down of all services.

5. Enter Y. The Shut Down Menu appears.

6. Select Shut Down Services and return console to OPERATOR MENU.

7. The following message appears:

Shutting down all services...
Do you wish to notify network users?

- Enter Y to notify users of the imminent shutdown.

- Enter N if you do not want to notify users of the shutdown.

Once the shutdown is complete, the Operator Menu appears.

8. Select System Maintenance. The System Maintenance menu appears.

9. Select Configure/Diagnose Server. The Server Configuration menu appears.

10. Select Install/Repair Fixed Logical Disk Drive. The system prompts you for the drive number (2-12) you want to install.

11. Enter the logical disk number and press ENTER. The system prompts you to perform a surface analysis of the new fixed disk:

- Enter Y if you are installing a WD1003 fixed disk (ST506, ESDI, or IDE) or you question the integrity of the new disk. The system scans the disk to find defective blocks. An informational screen appears.

- Enter N if you are installing a SCSI or RAID fixed disk subsystem. Go to step 19.

12. Press ENTER to continue. The system reports the number of bad blocks and displays the following prompt:

Do you wish to enter any defect information by byte offset (y/n)?

- Enter Y to enter bad blocks by cylinder/head/byte offset. Go to step 14. If you choose this format, the system may prompt you for the fixed disk interleave factor.

- Enter N to enter bad blocks by sector number. Go to step 13.

13. This prompt appears:

Do you wish to enter any defect information by sector number (y/n)?

- Enter Y to enter bad blocks by sector number. Go to step 14.

- Enter N to skip entering bad blocks. To continue installing the disk, go to step 19.

14. Depending on the format you chose, the system prompts you to enter the appropriate defect information for each of the following:

- Cylinder number

- Head number

- Byte offset from index or sector number

15. Enter the appropriate information.

16. The system prompts you to confirm that each bad block you enter is correct.

- Enter Y if the information is correct.

- Enter N if the information is incorrect. Repeat step 14.

17. When you have finished entering bad blocks, press ENTER at the prompt for a cylinder number. Respond appropriately to any additional prompts.

18. The system prompts that the surface analysis is complete. When ready to continue, press ENTER.

19. The server constructs a new file system on the additional disk. The new file system is the size of the disk but you can change the size and create other file systems at the prompt:

Logical disk 2 has a total capacity of 1300 MB.

The following file systems will be created on logical disk 2:

File System Size

first 1300MB

Do you wish to override these defaults and specify your file system sizes? (y/n):

Enter Y to specify file system sizes for the first and subsequent file systems.

After the file system is built, the Server Configuration menu appears.

20. Return to the System Maintenance menu and then return to the Operator Menu. Restart the server software.
