Applies to

  • ONTAP 9
  • Secd
  • CIFS
  • NFS
  • Microsoft Active Directory
  • Microsoft Active Directory Domain Controller (DC)
  • NTLM Authentication

Answer

Yes, the 'secd.dc.out.of.pipe.instances' alert indicates that the DC has run out of available named pipe instances to handle requests from ONTAP.
This situation can lead to the following impacts:
  • AD Server Communication:
    • The alert signifies that the DC is unable to process additional requests due to the exhaustion of named pipe resources.
    • This results in delayed authentication processes as ONTAP waits for available pipe instances.
  • NetApp CIFS/NFS Services:
    • Prolonged delays in authentication can lead to CIFS authentication failures.
    • Consequently, this impacts the ability of NetApp to provide CIFS services, potentially leading to client timeouts and access issues.
