1. Entering the commands hwstat hwstat v and sysstat v shows the disk status as disabled and not as initializing while the disk is being enabled This is confusing and can lead to a duplicate enable operation being performed Timeout for Invalid Schema File Bug 6411146 If you attempt to commit an invalid schema xm1 file with the mdconfig c command the CLI becomes non operational and eventually times out Sun StorageTek 5800 System Release Notes 5 MisleadingIndicator of Utilization Relative to Total Space Bug 6421305 Note the following with the df command m df reports raw storage utilization You can use df effectively to view raw storage statistics for each disk in the cluster Therefore used is not equivalent to the total number of Object bytes stored in the system For example it includes space consumed by data parity Object headers and footers query indexes and so on m df statistics are refreshed every three minutes Storage utilization statistics reflected by df are refreshed every three minutes a 15 of storage capacity is reserved for recovery When using df to view storage utilization be aware that the system reserves 15 of raw storage This space is available so data recovery can be completed should a node or disk fail on a full cluster Misleading Data Integrity Verified Message Bug 6421293 If you power up the system access the CLI and then enter sysstat a Data Integrity Verified indication appears2. 11 Service Contact Information 11 3 iv Sun StorageTek 5800 System Release Notes May 2006 Sun StorageTek 5800 System Release Notes This document contains important information about the Sun StorageTek 5800 system that was not available at the time the product documentation was published Read this document so that you are aware of issues or requirements that can affect the installation and operation of the Sun StorageTek 5800 System m Features in This Release on page 1 a List of Platform APIs on page 2 a Known Issues on page 2 m Release Documentation on page 11 m Service Contact Information on page 11 Features in This Release The Sun StorageTek 5800 system is an online storage appliance featuring a fully integrated hardware and software architecture in which the disk based storage nodes are arranged in a symmetric cluster The clustered and redundant design provides high availability good performance and exceptional data integrity The Sun StorageTek 5800 system provides the following features m Storage control data and metadata path operations distributed across the cluster to provide reliability and performance scaling m Total symmetry in both hardware and software No single point of failure with non disruptive serviceability that includes fail in place components for deferred maintenance m Optional storage of metadata associated with all data for easy reference and parallel
3. Configuration Bug 6405506 If you configure an SMTP server and a port in the CLI using the netcfg command the switch will not recognize the port you configured Sun StorageTek 5800 System Release Notes May 2006 Executing Configuration Changes with Reboot Bug 6406170 When you make a configuration change certain properties require a reboot to take effect Once the change is entered however you can no longer determine the current value since the netcfg command shows the new pending value instead You also cannot tell that the displayed value is a pending value and that a reboot is still required No CLI Error Message When System is Non Operational Bug 6241900 If you log in to the system enter the CLI help command and then enter additional commands such as version and sysstat an immediate exit from the login session results No error message is displayed Adding the v Option to Certain Commands Bug 6403938 Should you inadvertently add the v or verbose option to certain CLI commands such as hwcfg where its use is not supported the following error appears unknown error Can t find resource for bundle java util PropertyResourceBundle key common version name NullPointerException in Alert Code Bug 6408010 Should you use the wipe command a NullPointerException appears on the console The operation will continue despite the appearance of this error Inaccurate Disk Status Message Bug 6409249

At this point however the Data Doctor tool has not completed a lost fragment recovery cycle and is unable to determine whether or not all data fragments are indeed accounted for No Node Identifiers With sysstat verbose Bug 6421314 If you enter the sysstat command and its verbose option the system output that appears does not include node identifiers Updating the Schema During a Load Bug 6427699 If you attempt to update the schema using mdconfig while a system load is occurring the result is that the database becomes suspended in a create schema state Client API Issues This section describes known issues and bugs related to using the client API 6 Sun StorageTek 5800 System Release Notes May 2006 IllegalStateException Error With a QueryPlus Operation Bug 6395771 Harmless errors are printed to stdout during query operations with a select clause For a cluster they are displayed in the log For the emulator these errors are written to the shell where the emulator is launched Data Space Not Reclaimed in Emulator Bug 6403951 The emulator supports the Delete Metadata operation of NameValueObjectArchive delete and hc_delete_ez However the emulator does not remove the underlying data file when the last metadata record is deleted The semantics are correct but the underlying space is not reclaimed Emulator Installation Directory Must Not Contain Space Characters Bug 6407770 If you try to install t
6. Bug 6402543 When moving a rack there is no way to power all the components down since the CLI shutdown command powers down only the nodes Unable to Start or Shut Down the Database Bug 6392770 Starting up or shutting down the cluster without all nodes being online may force the query indexes to be rebuilt Until the rebuilding process is finished query results may be incomplete See the sysstat command for the status of the query engine Inconsistent Date Reporting Bug 6408658 If you attempt to determine when a file or directory was last modified or created be aware that there are inconsistencies in date reporting For example the directory listing get lastmodified might show a significant offset from Coordinated Universal Time UTC while the creationdate is about the same time without the offset These times should be similar or very close Node BIOS Issue Bug 6413587 When the Sun StorageTek 5800 node BIOS is booting up the following two conditions may occur m The BIOS fails to boot successfully and becomes non operational m The BIOS detects a false fan failure on one or more fans and shuts down Workaround Power on the node again through the front panel power switch If this does not fix the problem remove the power cord wait 30 seconds and then connect the power cord once more Sun StorageTek 5800 System Release Notes 9 Switch Failover Does Not Produce Switch Failover Alert Bug 6402478 Despite
