GFSN5010E
Base Group Mask and Deny ACL mismatch: Group Mask: h_digit0. Deny ACE: d_digit, WType: h_digit1, WId: h_digit2, AType: h_digit3, AFlag: h_digit4, AMask: h_digit5.

Explanation

The z/OS NFS Client, or the z/OS NFS Server, called the NFS to z/OS UNIX ACL conversion function. z/OS UNIX does not support storing a Mask ACL entry. Therefore, z/OS NFS dynamically computes the Mask ACL permission value from the Base Group Deny permissions. This requires that the Base Group Mask and Deny permissions must match. The function encountered an NFS Deny ACL entry whose Mask (permission) value does not match the Base Group Mask value. Mismatched values can not be supported by z/OS NFS. The ACLs cannot be converted and the request is terminated.

If this message occurs on the z/OS NFS Server, it means that a remote NFS Client is attempting to set ACL entries with mismatched NFS Base Group Mask and Deny ACL Mask (permission) values. This is not supported by z/OS UNIX.

If this message occurs on the z/OS NFS Client, it means that the z/OS NFS Client is attempting to manage ACLs for a remote NFS Server and the remote NFS ACL contains mismatched NFS Base Group Mask and Deny ACL Mask (permission values. This is not supported by z/OS UNIX.

In the message text: (primarily intended for IBM support personnel use)
h_digit0
The hexadecimal value of the NFS Base Group Mask ACL entry mask field.
d_digit
The 0-origin index of the NFS Base Group Deny ACL entry containing the error.
h_digit1
The 0-origin index of the NFS Base Group Deny ACL entry containing the error.
h_digit2
The hexadecimal value of the user, or group, id.
h_digit3
The hexadecimal value of the NFS ACL type field (see RFC3530).
h_digit4
The hexadecimal value of the NFS ACL flag field (see RFC3530).
h_digit5
The hexadecimal value of the NFS ACL mask field (see RFC3530).

System action

The request fails and normal processing continues.

Operator response

None.

System programmer response

None.

Programmer response

Check the remote system NFS ACL entries and update them to comply with the z/OS NFS ACL management restrictions. See Displaying and modifying remote file system access control lists for more information.
