SUSE Linux Enterprise Point of Service 11 Service Pack 1


The last maintenance update for SLEPOS11 SP1 contains soft raid 1 support. This is a small HOWTO on configure soft raid 1 for cash register.


Soft raid 1 is a new feature coming with the latest maintenance update.  Please install the latest SLEPOS and kiwi updates (recommended).

  1. Build a new image to get a new initrd.gz.
  2. Add or modify a scCashRegister object to the LDAP tree on Admin Server.
    The following Example shows how to add a new RaidScheme:

     Add to a new CashRegister:
        # --add --scCashRegister --base cn=global,o=foo,c=de \
         --cn cr-test-default --scCashRegisterName raid \
         --scPosImageDn cn=myRaid_test,cn=default,cn=global,o=foo,c=de \
         --scRaidScheme "/dev/sda /dev/sdb"

     Add to an existing CashRegister:
        # posAdmin --modify --scCashRegister \
        --DN cn=default_CR,cn=minimal,cn=default,cn=MyLocation,ou=MyUnit,o=foo,c=de \
        --scRaidScheme "1 /dev/sda /dev/sdb"
  3. Run the command "posldap2crconfig --dumpall" on Branch Server to write the changes to the config.MAC files.

Additional Information

It is also possible to modify manually the config.MAC file for testing propose:
Important are the following lines:
  • Raid Line:
  • First disk for local boot (grub)
  • Raid device name md1:
Example from a generated file:
# cat config.52\:54\:00\:12\:37\:17
POS_HWTYPE_HASH=dump by --dumpall
