Copying minidisk 01B4 to 11B4 ...

Note that FLASHCOPY did not succeed in every case, and the EXEC falls back to DDR. This is
not unexpected as the copying of the data from the previous EXEC had probably not
completed in the background of the disk subsystem.
Now the same golden image exists on S10RWMNT, S10RWTST and S10GOLD.
1.5.9 Cloning a read-write Linux system
You should now be ready to clone a read-write system. The CLONERW EXEC copies the 1B0, 1B1
and 1B4-1B8 minidisks from the S10GOLD system to a target user ID that must be specified.
To clone a read-write system, perform the following steps:
1. Create a new user ID LNX226 with the same size and numbered minidisks as the Linux
user IDs:
USER LNX226 PASSWD 256M 1G G
INCLUDE RORDFLT
OPTION APPLMON
MDISK 01B0 3390 0001 0060 DM63CB MR PASSWD PASSWD PASSWD
MDISK 01B1 3390 0061 0500 DM63CB MR PASSWD PASSWD PASSWD
MDISK 01B4 3390 0561 0550 DM63CB MR PASSWD PASSWD PASSWD
MDISK 01B5 3390 1111 0100 DM63CB MR PASSWD PASSWD PASSWD
MDISK 01B6 3390 1211 1019 DM63CB MR PASSWD PASSWD PASSWD
MDISK 01B7 3390 2230 2290 DM63CB MR PASSWD PASSWD PASSWD
MDISK 01B8 3390 4520 0489 DM63CB MR PASSWD PASSWD PASSWD
Bring the changes online, either via the DIRECTXA command, or via the appropriate “add”
command if you are using a directory maintenance product.
2. Create a parameter file on the CMSCLONE 192 disk (which is the Linux user ID’s read-only
191 disk). By default CMS accesses the 192 disk as D. The S10RWMNT parameter file on
CMSCLONE’s D disk is copied as a template, and the host name and IP address are
modified:
===> copy s10rwmnt parm-s10 d lnx226 = =
===> x lnx226 parm-s10 d
