Introduction
The Cisco SN 5428 Storage Router provides universal access to storage over IP networks. The storage router software controls the operation of the Cisco SN 5428 Storage Router. You can configure the software to provide one of two types of access to storage over IP networks; either SCSI routing or Transparent SCSI routing.
SCSI routing provides IP hosts with access to Fibre Channel (FC) storage devices, using iSCSI protocol. The iSCSI protocol is an IETF-defined protocol for IP storage (ips).
Note
With SCSI routing, storage device access is managed primarily in the SN 5428. (See Figure 1.)
Figure 1 SCSI Routing
Transparent SCSI routing provides IP hosts with transparent access to intelligent storage arrays using iSCSI protocol; that is, each IP host is presented as an FC host to an intelligent storage array. With transparent SCSI routing, availability of storage devices is managed primarily in the intelligent storage array. (See Figure 2.)
Figure 2 Transparent SCSI Routing
In addition to providing services for accessing storage over IP networks, the SN 5428 Storage Router software provides the following services:

IP Hosts
To ensure the best performance for the SN 5428 Storage Router and the iSCSI drivers, the extended windowing feature of TCP and the receive and transmit flow control feature of the Gigabit Ethernet driver should be enabled on all IP hosts connecting to the SN 5428. On the SN 5428 Storage Router, you can use the CLI show scsirouter all connection tcp command to display the current and maximum TCP window size for each connected host.
Graphical User Interface
The SN 5428's web-based GUI officially supports the following browsers:
The browser must be enabled to support JavaScript and style sheets.
iSCSI Driver Version Support
A Cisco SN 5428 Storage Router running software release 2.5.1 or later is compatible with an IP host running any Cisco iSCSI Driver version 2.1.1 or later; it is not compatible with an IP host running any Cisco iSCSI Driver version 1.8.x.

–
–
–
–
Failover by eligibility is enabled by default. However, failover by eligibility will not occur between SN 5428s in a cluster until all SN 5428s are running software capable of handling this new feature.
For example, if you upgrade one SN 5428 in a cluster, failover by eligibility will not occur until the other SN 5428 in the cluster is also upgraded. Until both SN 5428s are running software capable of handing failover by eligibility, failover will only occur if a critical resource is unavailable, or if all mapped targets are unavailable.

Limitations and Restrictions on SN 5428 Storage Router Clusters
This release includes the following restrictions on SN 5428 Storage Router clusters:
•
•
•
Important Notes
The SN 5428 Gigabit Ethernet ports, GE 1 and GE 2, can use either MT-RJ small form-factor pluggable (SFP) modules or LC SFP modules. The Cisco product numbers for those SFP modules are listed as follows:
•
•
The availability of the MT-RJ SFP modules may be limited; if they are unavailable, you can use LC SFP modules in place of the MT-RJ modules. If you are using LC SFP modules in place of MT-RJ SFP modules, make sure that you use the appropriate cable. For example, if you are connecting an LC SFP module in an SN 5428 to an MT-RJ connector in an external end system, switch, or router, you would need a cable with an LC connector at one end and an MT-RJ connector at the other end.
Caveats
Caveats describe unexpected behavior or defects in SN 5428 software releases. Severity 1 caveats are the most serious caveats; severity 2 caveats are less serious.
This document describes open and resolved severity 1 and 2 caveats and selected caveats of other severities.
•
•
Within the sections, the caveats are sorted alphanumerically by caveat number.
Note

Open Caveats
All the caveats in this section are open in SN 5428 software release 2.5.1.
Configuration-Mgmt
•
RIP settings cannot be restored from a saved configuration file.
Workaround: Use the GUI or the CLI to reconfigure RIP settings.
FC-Switch
•
Interrupting power during diagnostics may cause a device failure. When upgrading software from 2.2.x or 2.3.x to 2.5.1, critical diagnostic activities occur that cannot be interrupted. After setting the new software version and issuing the reboot command, the device will begin POST and then diagnostics. Interrupting the execution of diagnostics, or bypassing diagnostics (using the reboot fast command) may cause flash memory on the device to become corrupt. This is not field serviceable.
Workaround: Do not interrupt the boot process after issuing the reboot command. Do not use the reboot fast command when upgrading software.
•
When there is an active zone set, attempts to clear the local or fabric zoning database fail.
Workaround: Disable the active zone set, and then issue the command to clear the zoning database.
FC-Switch-Manager
•
Enabling the FC interface after performing an internal loopback test in diagnostic mode may fail to restore the interface to an operational state.
Workaround: After performing the internal loopback test, disable, enable and then reset the FC interface to restore it to an operational state. For example, issue the following CLI commands to restore the interface fc3 to an operational state after performing an internal loopback test in diagnostic mode:
[SN5428A]# no interface fc3 enable[SN5428A]# interface fc3 enable[SN5428A]# interface fc3 resetGUI
•
SN 5428 software download fails when using the HTTP Put File function from Microsoft Internet Explorer version 5.5 with service pack 2. The user may receive a "page cannot be displayed error" or the download may appear to hang. This is bug in Microsoft Internet Explorer.
Workaround: Use Microsoft Internet Explorer 6.0 to download SN 5428 software using the HTTP Put File function.
•
When a user attempts to remove a zone from a zone set using the GUI, a blank Modify FC Zoneset web page displays and the zone is not removed from the zone set.
Workaround: Use the CLI delete zoneset command with the zone keyword to remove the specified zone from the zone set.
•
When restoring configuration information for the integrated FC switch component from a saved configuration file, the "fcswitch zoning default" value is not restored. This value identifies the level of communication between the SN 5428 and devices in the fabric when there is no active zone set. Valid values are All or None.
Workaround: If the value in the saved configuration file differs from the current value, use the CLI or the GUI to reset the "fcswitch zoning default" value.
•
AAA configuration information is not propagated to other nodes in a high availability cluster when configuration is done via the SN 5428 GUI.
Workaround: After performing AAA configuration and maintenance via the GUI, issue one of the following CLI commands from the SN 5428 that is performing AAA management functions:
[sn5428a] save all bootconfig[sn5428a] save aaa bootconfig•
When using the GUI Put File functionality to upgrade SN 5428 software and the upgrade process fails because there is not sufficient space available, the GUI displays an error message indicating the process failed. However, the partially loaded version of software is not removed from the filesystem. If you subsequently attempt to download software via the CLI, the transfer appears to hang.
Workaround: Verify that there is sufficient space available (at least 30 MB) before attempting to upgrade SN 5428 software. If the GUI Put File fails due to lack of space, manually remove that version of software before attempting another download.
Other
•
The capacity of some target LUNs is erroneously displayed as 0 KB when a show devices command is issued. This can occur if a target rejects the SCSI Read Capacity command issued by the SN 5428.
Workaround: Issue the show devices rediscover command. This will force a retry of the SCSI Read Capacity to the target LUN.
SNMP
•
SNMP does not always return the correct value for the object ifLinkUpDownTrapEnable for the SN 5428 management or HA interfaces. It may report the value as enabled(1) when it should be reporting disabled(2).
Workaround: Use the CLI or the GUI to check the value of the SN 5428 trap setting for the interface.
Software-Mgmt
•
When using an HTTP server that requires authorization to access directories and files, the authorization fails when trying to download a new version of SN 5428 software using the CLI.
Workaround: Use the SN 5428 GUI HTTP functions to download new SN 5428 software versions.
•
The SN 5428 Storage Router may fail to boot successfully because the integrated Fibre Channel switch component does not retain the default IP address. This problem can only occur in two situations. The user will only encounter one of these situations.
The first situation occurs during diagnostics, when test 18 fails with the following message:
Starting -> 18 - FC switch startup Test...Waiting for switch to rebootFailed!curTest = 00018, error code = 06000000Test Number = HL 18Execution Count = 1Voltage Margin = NominalDate/Time of failure: TUE SEP 17 19:12:09 2002Error code = 0600-0000Severity = FatalFailed FC Switch logic ping commandFRU Replacement List = FC Switch Logic, CISCO SN5428, END.Failure address = 00000000Expected -> 00 00 <- ReceivedThe second situation occurs during initialization, when the Fibre Channel switch application attempts to ping the integrated switch components and diagnostics are disabled. In this situation, the following message displays:
"Switch ping check failed"In either of these situations, the user will be brought to the vxWorks console prompt.
Workaround: Contact Cisco TAC for more information on this defect.
Software-Other
•
Telnet sessions appear to hang or are terminated while extensive logging is occurring to the Telnet session. This may occur when failovers are being performed and extensive messages are being logged, or if debug level logging is enabled for the session.
Workaround: Press the Enter key several times, and the Telnet session will usually terminate. The user can then restart a Telnet session. The user can also close the hung Telnet window and simply start a new Telnet session in another window.
TCP-IP
•
When running with RIP enabled and overlapping subnet routes are being used, only one of the routes will be installed in the SN 5428 routing table. For example, if a route to 10.0.0.0/8 and a route to 10.0.0.0/24 are both learned by RIP, only one of the routes will be used.
Workaround: When RIP is enabled, do not use overlapping subnet routes.
Resolved Caveats
All of the caveats listed in this section are resolved in SN 5428 software release 2.5.1.
Configuration-Mgmt
•
NTP client initialization is not performed during startup, preventing the use of date and time services from an NTP server.
Workaround: Manually restart the NTP client after each reboot by reconfiguring the NTP server IP address (or name) used by the SN 5428 to query current time.
•
Executing the CLI command show tech support or show bootconfig may cause the SN 5428 to lock up. The UI task fails with a memory error if a configuration requires a large buffer to hold the target information being displayed.
Workaround: None.
FC-Switch
•
An EMC FC4700 CLARiiON array may not be able to login successfully to an FC interface on the SN 5428 when the interface is configured as F, FL, G or GL port types.
Workaround: Configure the SN 5428 port type as TL, with a mode of autobridge. For example:
[SN5428A]# interface fc1 type tl-port mode autobridge•
Fibre channel (FC) ports will not become active when targets or HBAs are connected.
Workaround: Lock down the link speed on the affected FC interfaces, if possible. For example, if the FC interface is connected to a 1 Gigabit target or HBA, explicitly set the link speed on the FC interface to 1 Gigabit.
GUI
•
The SN 5428 may unexpectedly restart when using the GUI to add a target to a SCSI routing instance.
Workaround: If the problem occurs, use the CLI to add targets to SCSI routing instances.
SCSI
•
The SN 5428 stops traffic and displays the following errors:

•
While running traffic to XIOTech disk devices attached to the SN5428 FC port, and power cycling other SN5428s on the switch, data corruption to one disk on the XioTech array was detected. The data corruption occurred while reading data from the device; data was returned incorrectly from the disk. Subsequent reads of the same information worked properly. This problem is extremely rare.
Workaround: Currently, there is no known workaround for this problem. If corruption is detected, data can be re-read correctly from the disk device. Avoid pulling cables or power cycling SN 5428s while traffic is running to these types of disk devices.
•
Deleting targets in transparent mode can create an out-of-sync condition between the standard SN 5428 displays and SCSI trace (tfestatus) information.
Workaround: None.
SNMP
•
A memory leak may occur when walking the CDP MIB. A bulk walk that traverses cdpVTPMgmtDomain has caused a leak of approximately 1.2KB.
Workaround: Avoid bulk walks of the CDP MIB.
Software-Mgmt
•
The TFTP download of a file does not appear to terminate. This can occur if the network connection drops while downloading a file via TFTP to the SN 5428 and the network connection is never reestablished. The background download progress indicator is not being correctly informed that the TFTP download process has failed and the progress indicator continues to display.
Workaround: Either reestablish the network connection, or reboot the SN 5428 Storage Router.
•
When attempting to update SN 5428 software, an HTTP download fails with the following message:
Can't download software: TarPostFail:The download fails because the file size of the software download exceeds a predefined maximum image size.
Workaround: When upgrading from either release 2.2.2 or 2.3.1 to release 2.5.1, download the software from the TFTP server, or use the GUI Put File facility to move the software to the SN 5428. The file size limitation is removed in release 2.5.1 software.
Software-Other
•
If you are using TFTP for the software download process and receive a TFTP error, the SN 5428 may restart. For example, if you are attempting to download a specific version of software and the file cannot be found on the TFTP server, TFTP returns an error. During the cleanup process, a memory exception causes the SN 5428 to reboot.
Workaround: Verify that the software version to be downloaded is on the TFTP server. Use the download software command with the version keyword, rather than the filename keyword.
Documentation Updates
This section describes corrections to the Cisco SN 5428 Storage Router Release 2.5 documentation set since initial publication.
•
The fcswitch devlog enable command is a new command, added as part of the resolution to caveat CSCdy77012. To enable development logging for the integrated Fibre Channel (FC) switch component, use the fcswitch devlog enable command. To disable development logging, use the no form of this command. This command is an Administrator mode command.
fcswitch devlog enable
no fcswitch devlog enable
The fcswitch devlog enable command is designed for debug purposes, and should be used under the guidance of a Cisco Technical Support professional.
•
The fcswitch log interface command is a new command, added as part of the resolution to caveat CSCdy77012. To restrict the integrated FC switch logging to a specific port (fc1 through fc8), use the fcswitch log interface command. To remove the restriction, use the no form of this command. This command is an Administrator mode command.
fcswitch log interface fc?
no fcswitch log interface fc?
The fcswitch log interface command is designed for debug purposes, and should be used under the guidance of a Cisco Technical Support professional.
•
The fcswitch syslog enable command is a new command, added as part of the resolution to caveat CSCdy77012. To enable system logging for the integrated Fibre Channel (FC) switch component, use the fcswitch syslog enable command. To disable system logging, use the no form of this command. This command is an Administrator mode command.
fcswitch syslog enable
no fcswitch syslog enable
The fcswitch syslog enable command is designed for debug purposes, and should be used under the guidance of a Cisco Technical Support professional.
•
The interface fc? reset command is a new command, added as part of the resolution to caveat CSCdy77012. To disable and then enable the specified FC interface (fc1 through fc8), use the interface fc? reset command. This command is an Administrator mode command.
interface fc? reset
This command is functionally equivalent to issuing a no interface fc? enable command, followed by an interface fc? enable command.
•
The interface fci? devicediscoverytimer command is a new command, added as part of the resolution to caveat CSCdy69379. To enable the SN 5428 internal Fibre Channel (FC) interfaces to perform background device rediscovery for all attached FC targets at specific time intervals, use the interface fci? devicediscoverytimer command. This command is an Administrator mode command.
interface fci? devicediscoverytimer nn
The device discovery timer is set in minutes. The default value is 0, indicating that automatic background device rediscovery is disabled.
Use this command to enable automatic device rediscovery on a periodic basis in environments where LUNs can be created on FC targets, but no event occurs to cause devices to be rediscovered. This situation may occur with certain RAID controllers or virtualization type devices.
You do not need to issue the interface fci? devicediscoverytimer command for both internal FC interfaces. When you enable automatic background device rediscovery for one internal FC interface (for example, fci1), the same setting is enabled for the other internal FC interface (for example, fci2).
[SN5428A]# interface fci2 devicediscoverytimer 20To disable automatic background device rediscovery, set the device discovery timer interval to 0. (This is the default setting.) For example:
[SN5428A]# interface fci2 devicediscoverytimer 0When automatic background device rediscovery is enabled, use the show interface command with the stats keyword to display the current device discovery timer configuration. In the following example, the SN 5428 will perform background device rediscovery every 10 minutes.
[SN5428B]# show interface fci1 statsloop: LOOP READYconnection: F PortData Rate: 2 Gb/sport id: 0x20f00ALPA: 0x0firmware: READY. . .
Note
•
On page 11-339 of the Cisco SN 5428 Storage Router Software Configuration Guide, three keywords should be added to the show debug fcswitch command. The memory keyword displays memory usage for the integrated FC switch component. The tech-support keyword displays technical support information for the integrated FC switch component. The clish keyword, followed by the appropriate quoted switch command, displays internal operational information for the integrated FC switch component.
The syntax of the modified command is:
show debug fcswitch {all | brief | memory | tech-support}
show debug fcswitch clish text
Note
•
On page 11-120 of the Cisco SN 5428 Storage Router Software Configuration Guide, add the following paragraph at the end of the "Usage Guidelines" section.
Before changing the default behavior, disconnect any ISL links to other fabric entities to prevent unintended disruption of fabric traffic.
•
On page 8-3 of the Cisco SN 5428 Storage Router Software Configuration Guide, the second paragraph under the section "Login Authentication" is incorrect and should be removed. Enable authentication, not Login authentication, extends to users attempting to access the SN 5428 Storage Router via FTP.
The paragraph should be corrected and added as the second paragraph in the "Enable Authentication" section, also on page 8-3 of the Cisco SN 5428 Storage Router Software Configuration Guide, as follows:
If the SN 5428 is configured to allow FTP access, Enable authentication also authenticates users attempting to login and establish an FTP session with the SN 5428.
•
On page 11-347 of the Cisco SN 5428 Storage Router Software Configuration Guide, the "Usage Guidelines" section incorrectly identifies the SN 5428 FC initiator interfaces as fci0 and fci1. The second paragraph should be corrected to read as follows:
The output of this command is limited to devices that are visible to the SN 5428 FC initiator interfaces (fci1 and fci2).
•
On page 11-66 of the Cisco SN 5428 Storage Router Software Configuration Guide, the port type keyword following type g-port in the "Syntax Description" table for the debug interface fc? command is incorrect. The port type keyword should be changed to type gl-port. The description of the keyword is correct.
•
On page 11-407 of the Cisco SN 5428 Storage Router Software Configuration Guide, the "Usage Guidelines" section incorrectly indicates the maximum number of concurrent CLI management sessions is 16. The sentence should be corrected to read as follows:
There are a maximum of eight concurrent CLI management sessions per SN 5428.
•
On page 9-1 of the Cisco SN 5428 Storage Router Software Configuration Guide, the first paragraph in the "Prerequisite Tasks" section should be updated to read as follows:
All SN 5428 Storage Routers that will participate in a cluster must have connectivity to the same hosts and the same storage systems, and must be connected to each other through their management and HA interfaces. At least one of the interface connections (management or HA) must be live; you cannot connect SN 5428s in a cluster using crossover cables.
•
The URL listed on page 10-20 of the Cisco SN 5428 Storage Router Software Configuration Guide Release 2.5, for password recovery procedures may not include procedures for the SN 5428. If you require assistance in recovering a lost console password and cannot locate the appropriate procedures at the documented URL, contact the Cisco Technical Assistance Center. (See the "Obtaining Technical Assistance" section for details.)
•
