I'm trying to reset the counters for 'Pending IOs' and the following command isn't working: nss /ZLSSPoolIOr=_summary.

I got this command from TID#3775622.

When I type this at the server console I get the following output:

Oct 1, 2008 10:07:41 am NSS<NSSLIB>-3.26-212: pcmdline.c[694]
Option "/ZLSSPoollOr=_summary" is unknown for the current NSS configuration and may require other NSS modules to be loaded.

We're running NW v6.5 sp7. The NSS version is the following:

FS1:nss version
NSS: Enabled
Version: 3.26 (Build 1062)
