Release Abstract This document serves as the Release Notes for the Acopia FreedomFabric™ Network Operating System (NOS), version 2.07.001 (shortened to “2.7.1” in these notes). The FreedomFabric™ NOS runs on the Acopia Adaptive Resource Switch (ARX®). Console Access To access the Command-Line Interface (CLI) through the Console interface, use a terminal-emulation program (such as HyperTerminal) and a console cable provided by Acopia Networks.
Acopia Networks, Inc. New Features Release 2.7.1 is a maintenance release for release 2.7.0. This release corrects anomalies in the 2.7.0 release. It does not offer new features. Upgrade Paths You can upgrade to 2.7.1 from any of the following releases: • 2.4.3, • 2.5.1, • 2.5.2, • 2.6.0, or • 2.7.0. New/Updated Certifications There are no new client or file-server operating systems certified for use with the ARX. For customers upgrading from Release 2.4.
Acopia Networks, Inc. 2.7.0 Features This section applies to installations that are upgrading from Release 2.6.0 or earlier. Release 2.7.0 added three features, also included in this release: • Persistent statistics for shadow-copy rules after failed runs of the rule, • enhanced resiliency for shadow-copy runs, and • improvements to the output for the show active-directory CLI command, to help with diagnosis of Active-Directory issues. 2.6.
Acopia Networks, Inc. • Time Windows for Log Collection – You can focus the collection of log messages by choosing an optional start time and end time. Refer to the documentation for the CLI command, collect logs. • Monitoring for CIFS-Client Activity – A new CLI command, show cifs-service client-activity, shows details about a CIFS-client connection to the ARX, as well as the proxy connections from the ARX to the filers behind it. 2.5.
Acopia Networks, Inc. show reports command. Clients experience degraded performance in these volumes until the upgrades are completed. After the upgrade, any directory with “~” in its name is accessible to NFS clients only. If your CIFS clients require access to one or more of these directories, run sync files for each of them. The sync files utility checks the volume’s back-end filers for any FGNs that collide with the directory name(s), and it clears the NFS-only status if no collision is found.
Acopia Networks, Inc. (“longnameddirectory”) actually reside on the other share’s directory (with the actual name of “LONGNA~1”). Clients cannot access the files unless someone runs another sync files operation. (28748) • A ron evict command can result in a growing packet storm among the RON’s remaining ARXes, possibly resulting in one or more ARX reboots.
Acopia Networks, Inc. • NSM processors occasionally fail with a core file. (27987) • Cannot press for prompts through customer’s Java SSL terminal. (28368) • Metadata-Inconsistency reports do not report large directories correctly. (27229) • An ARX with a large number of exports (more than 7200) sends an excessive number of nsmResourceThreshold traps. This resource trap is inappropriate for exports. (28442) • The delete capture command causes a “Dynamic SQL Error” in the syslog.
Acopia Networks, Inc. • The policy engine continues running on the backup switch in a redundant pair, resulting in multiple “POLICY_PDP-0-3-POLICY_DB_OP_FAILED” messages in the syslog. (27875) • Clients are unable to access ARX CIFS services through an SSL VPN. (27729) • Kerberos authentications/logins are excessively slow (up to two minutes long) on an extremely busy ARX. (27983) • NSM processors occasionally fail, writing a core file, when they have a CIFS connection to an EMC file server.
Acopia Networks, Inc. • ARX volumes declare their back-end shares “offline” when write probes fail for 40 seconds. Multiple probe types should fail over a longer period for a share to be declared offline. (27400) • A volume with cifs path-cache enabled rejects all requests for the “/” path (such as mount requests) from Mac Dave clients. (27404) • If a managed volume’s metadata filer is slow for an extended time, the volume may spontaneously reimport.
Acopia Networks, Inc. • In the show namespace output for a namespace that is importing, the import status shows “N/A” for the first few seconds. (12377) • A misleading error may appear when using the GUI to remove a volume. (25096) • The Create Virtual Service wizard does not allow you to change the service’s namespace after you have defined one export from it. (25107) • You cannot enter an Organizational Unit (OU) with a name longer than 71 characters from the GUI. (25108) In Release 2.5.
Acopia Networks, Inc. Known Anomalies This release contains the following known anomalies. Problem Description Alarming error messages and logs appear during a firmware upgrade. (19365, 26774) The following message appears in the CLI after you invoke and confirm a firmware upgrade: ARXa6K# firmware upgrade all Confirmation of this command commences a firmware upgrade on the entire chassis. During the upgrade process, the chassis reboots automatically to complete the upgrade process.
Acopia Networks, Inc. Problem Description The CLI show clock output does not always show the correct time after a time-zone change. (24526) You can use the clock timezone CLI command to set the time zone of the ARX. On rare occasions, the output from the show clock command does not show the correct time after this change.
Acopia Networks, Inc. Redundancy Problem Description Spurious errors appear in the syslog after an NSM failover. (25782) NSM processors have redundant peers, even in an ARX that is not configured for overall redundancy. If an NSM processor fails, its peer processes packets for both. If nsm recovery is configured, the failed processor comes back online and waits to take over for the running processor.
Acopia Networks, Inc. NSCK and Sync-Files Problem Description NSCK reports do not identify “marked” multi-protocol directories where you should run a sync files operation. (23891) Some multi-protocol (NFS and CIFS) directories are “marked” for special processing. These directories contain files and/or subdirectories one of these naming issues: • the name resembles a Filer-Generated Name (FGN, such as “myfile~1.txt”), or • the name produces an FGN on its back-end filers (such as “my:file.
Acopia Networks, Inc. Shadow Volumes Problem Description A cryptic error appears in the shadow-copy report when the source volume is undergoing an nsck … rebuild. (20148) If the source volume is being rebuilt during a shadow copy, the shadow copy fails appropriately.
