Problem
I have installed an additional hard disk using the "mkdev hd" utility. I now need to remove (de-configure) the additional drive.
-or-
I followed the instruction in Technical Article 105052, "How can I remove and reinstall an additional hard disk on SCO OpenServer 5?", and when I relink I get:
idmkreg : error updating space.c for Sdsk
The information in this article is based on a two-drive system where you want to remove the second drive. If you have more than two drives, you can still use this information. Simply use the correct number for the last drive on your system when following these steps. For example, if you have a three-drive system, you would replace hd10 with hd20 in the steps listed below, and all other references to 1 would be replaced with 2 to remove the third disk drive.
WARNING:
THIS INFORMATION IS FOR REMOVING THE LAST DISK THAT WAS ADDED TO THE SYSTEM.DO NOT USE THIS INFORMATION TO REMOVE DISKS IF THEY ARE NOT THE LAST DISK ADDED TO THE SYSTEM. If you need to remove configuration for more than one disk, follow the steps to remove the last disk first and work your way back (that is, hd3*, then hd2*, then hd1*).
Solution
To remove configuration files for additional hard drives on SCO OpenServer 5.0.4, do the following:
1. Remove the special device files for the additional hard drives:
# rm /dev/hd1*
# rm /dev/rhd1*
# rm /dev/dsk/1s*
# rm /dev/rdsk/1s*
NOTE: "hd1*" is the naming convention for the second hard drive and "hd2*" is for the 3rd hard drive and so forth.
For SCSI hard drive, you may need to run:
# mkdev .scsi
Choose to Remove a SCSI device.
Choose the Hard Disk.
Enter the proper Target ID number, Host adapter number and LUN number to remove that SCSI hard disk device.
As an added verification, edit the /etc/conf/cf.d/mscsi file. You should have only one line item for the hard disk (listed as "Sdsk" under the attach column). If there are excess entries for Sdsk, remove these lines.
2a. Check the /etc/conf/node.d/Sdsk file for extra entries. Remove all
entries of the type listed below:
Sdsk dsk/1s0
Sdsk hd10
Sdsk rdsk/1s1
Sdsk rhd10
NOTE: There will not always be an Sdsk entry in the /etc/conf/node.d directory. If you do not have this entry, go to the next step.
2b. Check the /etc/conf/node.d/hd file for extra entries. Remove all entries of the type listed below:
hd dsk/1s0
hd dsk/1s1
hd dsk/1s2
hd dsk/1s3
hd dsk/1s4
hd dsk/1sC
hd dsk/1sD
hd dsk/1sE
hd dsk/1sF
hd dsk/1sG
hd dsk/1sH
hd dsk/1sI
hd dsk/1sJ
hd dsk/1sa
hd dsk/1sd
hd hd10
hd hd11
hd hd12
hd hd13
hd hd14
hd hd1a
hd hd1d
hd rdsk/1s0
hd rdsk/1s1
hd rdsk/1s2
hd rdsk/1s3
hd rdsk/1s4
hd rdsk/1sC
hd rdsk/1sD
hd rdsk/1sE
hd rdsk/1sF
hd rdsk/1sG
hd rdsk/1sH
hd rdsk/1sI
hd rdsk/1sJ
hd rdsk/1sa
hd rdsk/1sd
hd rhd10
hd rhd11
hd rhd12
hd rhd13
hd rhd14
hd rhd1a
hd rhd1d
3. Modify the Sdsk driver to remove the entries for the additional disk drives. Edit the /etc/conf/pack.d/Sdsk/space.c file and remove the additional disk entries between the lines that contain the word PROBE,located at the bottom of the file.
========================================================
Example of a space.c file with two disk drive entries:
========================================================
/* Probe routine return values, the marker comments must be
kept in place so that the mkdev script can patch up this
file correctly
*/
/*_PROBE_START_*/
#define Sdsk0 155648 /* Sdsk0 */
#define Sdsk1 155649 /* Sdsk1 */
int SdskProbe[] = {Sdsk0,Sdsk1,0};
/*_PROBE_STOP_*/
/* End probe routine return values */
Remove the define statement for Sdsk1 or the disk(s) you want to remove from the system, and remove the same entry from the SdskProbe line.
=============================================================
Example of the space.c file after removing the Sdsk entries:
=============================================================
/* Probe routine return values, the marker comments must be
kept in place so that the mkdev script can patch up this
file correctly
*/
/*_PROBE_START_*/
#define Sdsk0 155648 /* Sdsk0 */
int SdskProbe[] = {Sdsk0,0};
/*_PROBE_STOP_*/
4. Edit the /etc/conf/pack.d/Sdsk/device.dat file to remove the entry for the disk you want to remove from the system.
============================================================
Example of a device.dat file with an additional hard disk:
============================================================
FILE_FORMAT:
version=1
Sdsk0:
INDEX=Sdsk0
PATH=node0,node1
node0=D_SUBSYS,SCSI Disk,0,D_HARDDSK_SUBSYS,,NULL
node1=D_UNIT,SCSI Drive 0,0,0,D_RANDOM_ACCESS D_NODE,NULL
D_USER_MSG=SCSI Disk Drive,0,0,,NULL
D_BLOCK_NODE = 0
D_CHAR_NODE = 0
Sdsk1:
INDEX=Sdsk1
PATH=node0,node1
node0=D_SUBSYS,SCSI Disk,0,D_HARDDSK_SUBSYS,,NULL
node1=D_UNIT,SCSI Drive 1,0,1,D_RANDOM_ACCESS D_NODE,NULL
D_USER_MSG=SCSI Disk Drive,0,0,,NULL
D_BLOCK_NODE = 64
D_CHAR_NODE = 64
===============================================================
Example of a device.dat file after removing the Sdsk1 entries:
===============================================================
FILE_FORMAT:
version=1
Sdsk0:
INDEX=Sdsk0
PATH=node0,node1
node0=D_SUBSYS,SCSI Disk,0,D_HARDDSK_SUBSYS,,NULL
node1=D_UNIT,SCSI Drive 0,0,0,D_RANDOM_ACCESS D_NODE,NULL
D_USER_MSG=SCSI Disk Drive,0,0,,NULL
D_BLOCK_NODE = 0
D_CHAR_NODE = 0
5. Remove the nodes for the filesystems that are on the disk that you want to remove from the system. These nodes are located in the /dev directory and consist of both the character and block node entries. For instance, if the disk you are removing has two filesystems then you would need to remove four nodes. As an example, if the two filesystems are named u1 and u2, you should remove the file nodes u1, ru1, u2 and ru2. For this example, enter the following:
# rm /dev/u1 /dev/ru1 /dev/u2 /dev/ru2
While this might be considered an optional step, if you are going to add this disk back to the system and you want to use the same names for the filesystems, divvy will not let you create filesystems with names that already exist on the system. Additionally, it is good administration to keep the /dev directory free of unused entries.
6. Modify the /etc/conf/cf.d/sysRegistry file. Remove the entry corresponding to hard disk(s) you want removed. The entry for a second SCSI hard disk would look something like this:
Sdsk1:
INDEX=99328
PATH=node0,node1
node0=15,SCSI Disk,0,4,0,NULL
node1=16,SCSI Drive 1,0,1,34,NULL
D_USER_MSG=17,SCSI Disk Drive,0,0,0,NULL
D_BLOCK_NODE=3,hd10,0,0,0,NULL
D_CHAR_NODE=5,rhd10,0,0,0,NULL
Remove all lines and save the file.
NOTE: There will not always be an Sdsk entry in the /etc/conf/cf.d/sysRegistry file. If you do not have this entry, skip this step.
7. Check the /etc/conf/cf.d/hdlist for extra entries and remove as necessary:
=========================================================
Example of a hdlist file with an additional hard disk:
=========================================================
0 /etc/conf/node.d/hd 0
1 /etc/conf/node.d/hd 64
========================================================
Example of a hdlist file after removing extra entries:
========================================================
0 /etc/conf/node.d/hd 0
8. Relink and reboot.
# cd /etc/conf/cf.d
# ./link_unix
# shutdown -g0 -y
Your system should now be cleared of the additional hard drive's configuration. |
