Navigating to the 

 tab of the 

Windows 

utility gives the administrator the ability to disable the NIS/PCNFSD 

mapping on a client-by-client basis by selecting 

.

The domain server must be at least Windows 2003 or above to support 

RFC 2307 mapping.

Setting Up Restrictive ACLs

1

When setting up restrictive ACLs on a SNFS file system, it is important to 

understand how SNFS system services are run, especially the account 

under which the services are run. The Windows default account is the 

local administrator account, but this can be changed on the Properties tab 

of each system service.
When sharing restricted file systems, the account under which SNFS 

system services are run must be included in the ACL for the root of the 

file system and all other shares associated with the SNFS file system. 

Doing this allows the shares to be re-shared upon reboot.

Default Single-Path I/O Retry Behavior

The I/O retry behavior has changed as of StorNext 3.1.2. In prior releases, 

when only a single path to the storage existed and an I/O error was 

returned by the disk device driver, StorNext failed the I/O operation. 

Beginning with version 3.1.2, by default StorNext continuously retries I/

O operations until they succeed, regardless of the number of I/O paths. If 

desired, you can override this new behavior by using the new I/O Retry 

Time feature. For additional information about I/O Retry Time, consult 

the mount_cvfs man page or the Windows help file.
