It comes from some backported stuff in the 2.6.32.12-0.7.1 SLES kernel that the
XCP kernel is based on. The Areca driver expects that this enum needs defining
for 2.6.32 and earlier kernels whereas the SLES and XCP kernels (and RHEL
probably based on the "!defined(RHEL_RELEASE_CODE)" bit) already have it
defined hence the redefinition error. FWIW this would happen on SLES with
2.6.32 as well.
#if !defined(RHEL_RELEASE_CODE) && LINUX_VERSION_CODE < KERNEL_VERSION(2, 6, 33)
enum {
SCSI_QDEPTH_DEFAULT, /* default requested change, e.g. from
sysfs */
SCSI_QDEPTH_QFULL, /* scsi-ml requested due to queue full
*/
SCSI_QDEPTH_RAMP_UP, /* scsi-ml requested due to threshhold
event */
};
#endif
You can simply remove this or cause the #if to always give false, e.g.:
[root@localhost arcmsr.1.20.0X.15-111012]# diff -up arcmsr.h.orig arcmsr.h
