Environment

Situation

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.

Resolution

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

Configure:

Build a new image to get a new initrd.gz.
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:
    # posAdmin.pl --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"
Run the command "posldap2crconfig --dumpall" on Branch Server to write the changes to the config.MAC files.
