Changing the Name of the Target System
To perform the steps in this procedure, the target system should be IPLed second level on the running system.
- On the target system, log on to the MAINTvrm user ID.
- Select a name for the target system. The target system name must be 1-8 alphanumeric characters and must start with a letter. The name must not contain any blanks and must not be NOSYS or NOSSI.
- Update the System-Level Product Inventory Table
(VM SYSPINV file) with the target system name.
- Link to and access the PMAINT 41D minidisk in write mode:
link to pmaint 41d as 41d w access 41d fm
- Make a backup copy of the VM SYSPINV file. XEDIT the VM SYSPINV
file using the WIDTH option to avoid accidentally truncating data
in the file:
Change all occurrences of the source system name (on the :SYSTEM. tag) to the target system name. Save the updated VM SYSPINV file.xedit vm syspinv (width 120
- Do not release the PMAINT 41D minidisk. There are additional files on the PMAINT 41D minidisk that must be updated.
- Link to and access the PMAINT 41D minidisk in write mode:
- Update the SYSTEM CONFIG file with the target system name.
- Link to and access the PMAINT CF0 minidisk in write mode:
link to pmaint cf0 as cf0 w access cf0 fm
- Make a backup copy of the SYSTEM CONFIG file. XEDIT the SYSTEM CONFIG file and change all occurrences of the source system name to the target system name. Save the updated SYSTEM CONFIG file.
- Run the CPSYNTAX utility to validate the changes you made to the
SYSTEM CONFIG file:
cpsyntax system config fm
- Link to and access the PMAINT CF0 minidisk in write mode:
- Update the VMSES/E service inventory files with the target system
name.
- Access the MAINTvrm 51D minidisk.
- Make a backup copy of the System-Level Service Update Table (VM
SYSSUF file). XEDIT the VM SYSSUF file using the WIDTH option to avoid
accidentally truncating data in the file:
Change all occurrences of the source system name (on the :PRODLEV. tag) to the target system name. Save the updated VM SYSSUF file.xedit vm syssuf (width 120
- Locate and make backup copies of all the Service-Level Production
Status Tables (files with a file type of SRVPROD) on the MAINTvrm 51D
and PMAINT 41D minidisks. XEDIT each SRVPROD file using the WIDTH
option to avoid truncating data in the file:
Change all occurrences of the source system name (on the :STAT. tag) to the target system name. Save the updated SRVPROD file.xedit compname srvprod (width 120
- Log off the MAINTvrm user ID.
- Update the recovery SFS server with the target system name.
- Log on to the recovery SFS server, VMSERVR.
The default password is WD5JU8QP.
To stop the server, enter:
STOP
- XEDIT the VMSERVR DMSPARMS file (located on the VMSERVR 191 minidisk). Change the LUNAME to match the target system name. Save the updated file.
- Update the CRR log minidisk with the target system name:
fileserv crrlog 306 307
Note: 306 and 307 are the default minidisks for the recovery server defined in the VMSYSR POOLDEF file (the VDEVS assigned on the DDNAME=CRRn statements) on the VMSERVR 191 minidisk. If your recovery server is using minidisks other than the defaults, adjust the FILESERV command accordingly. - Restart the server and disconnect:
profile #cp disc
- Log on to the recovery SFS server, VMSERVR.
The default password is WD5JU8QP.
- Log on to the MAINTvrm user ID.
- Shut down the target system:
shutdown
- When the shutdown is complete, IPL CMS on your first-level system user ID.
- While logged on to your first-level system user ID, rewrite or
remove the system ownership information on your spool and page volumes.
For each spool and page volume, enter the following command:You will be prompted to confirm the format command. When cylinder 0 is formatted, you need to reenter the allocation for the volume.
cpfmtxa vol_addr vol_label owner nossi target_system_name
For a spool volume, enter:spol 0-end end
For a page volume, enter:page 0-end end
- IPL the target system second-level to make sure it will come up.
Enter the following sequence of commands:
Note the console address. If the address is not 20, redefine it:system clear term conmode 3270 q cons
IPL the system:define conaddr 20
Check the SAPL screen to make sure the IPL parameters are correct. Addipl target_RES_addr clear loadparm 20
cons=20
to the IPL parameters and press F10 to complete the load. You will be running on the OPERATOR user ID. - You are now ready to start using the target system. You can shut it down if you intend to bring it up in another location, such as its own LPAR or another user ID. Otherwise, disconnect from the OPERATOR user ID and log on to the MAINTvrm user ID.
