Change CPU Mask or Hugemem Size

If you specify incorrect hugemem size -the size that is bigger that can be allocated on the system then the product can’t start properly. In case of incorrect hugemem the following error is displayed in the syslog:

xnr_plt_set_hugemem: ERROR: Node 0, hugepages 2048kB requested 450000, allocated 4578

If the product is installed with wrong CPU mask or hugemem parameters and cannot start as a result you can change these parameters by calling the xiRAID Opus binary with other CPU mask and hugemem values. The operation shall be run with superuser (root) rights. --xnr-nostart flag should be used. Here is an example to update the CPU mask to 0xFFFF and hugemem size to 32768 megabytes:

# <path_to_installed_binaries>/xnr_xiraid.1.0.0 -m 0xFFFF --xnr-hugemem 32768 --xnr-nostart

or if you allowed symlink creation on the installation step:

# xnr_xiraid -m 0xFFFF --xnr-hugemem 32768 --xnr-nostart
