There are changes between the kernel shipped with SLES 10 and that

do), you'll have to adjust them. Looks like the link you're after
changed from
/sys/devices/dcssblk/PERFOUT/block:dcssblk0
to
/sys/devices/dcssblk/PERFOUT/block/dcssblk0
(if I am reading the traffic correctly).
The recent distro major releases (SLES11 SP1, RHEL 6) have their kernel
built without CONFIG_SYSFS_DEPRECATED_V2 [1] which seems correct and has
the consequences on sysfs layout that you encountered.
This applies to all kinds of device classes, e.g. block or network [3].
Indeed the former symlink was replaced with two containing directories,
the name of the outer depending on the device class.
There are some rules for user space tooling working with sysfs to get it
future-proof [2]. Maybe they are of help.
