Re: Quorum Elert Instruction Zip

NOTE: The firmware package in this version has been zipped with a password using 7-Zip. It must be unzipped before uploading to the FlashSystem. To obtain the password, contact IBM support.IBM Support personnel should see this link for more information.
IBM FlashSystem V9000 product resources guide users through the various features and components of the storage system, including usage and troubleshooting guides.To read about this storage system and learn how to use or troubleshoot, see IBM Knowledge Center for IBM FlashSystem V9000 or visit the IBM Redbooks website for the IBM FlashSystem V9000 Product Guide.
After initial configuration of the hardware is complete, IBM strongly recommends that you make sure that your IBM FlashSystem firmware is up-to-date.Visit IBM Fix Central using the link below to see if any updates are available for your system.
The following fixes are made available with release 1.6.0.0. To view fixes from earlier releases, see the Release history.Available firmware releases are listed on IBM Fix Central. For issue severity definitions, see the Bug severity legend.
FLASH-25164 - In the very unlikely event of not having enough rebuild tracking structures, the interface controller will now properly return the SCSI BUSY status, which will indicate the command needs to be retried. (S3)
If you are upgrading to this release and your system is healthy, you can perform a Concurrent Code Upgrade (CCU). A CCU is a non-disruptive upgrade and is the preferred upgrade method. For general instructions on performing upgrades, refer to the FlashSystem Knowledge Center.
CCU is a non-disruptive upgrade, which means that the system remains online throughout the process and that you can continue to access data normally.As a precaution, it is recommended that the upgrade occur during a time of reduced traffic. During the upgrade, the interface adapters in each canister are taken offline temporarily to be upgraded.This might impact performance or throughput. The impact is more noticeable under heavy load conditions. With a properly configured multi-path configuration, access to your data is always maintained.
Running the ugprade test utility is a required step before concurrent upgrade in firmware versions after 1.2.0.11. The utility checks for problems in the system that might prevent the upgrade from completing successfully and either warns the user or blocks the user from proceeding. IBM Support recommends that all users planning to upgrade run the utility a full day in advance so that any issues called out by the utility can be remedied without delaying the planned upgrade.
Important: Before you begin the upgrade, we recommend that you perform a backup of your data and a backup of the FlashSystem configuration. To back up the configuration, log into the cluster management IP address and issue the following command using admin-level authority:
Optionally, you can copy the configuration backup file from the FlashSystem to your workstation using secure copy (scp) on Linux or PuTTY secure copy (pscp.exe) on Windows as in the following examples:
Posted along with the release notes and upgrade files on Fix Central are md5sum text files. These files exist for each update file so that the user can verify that the update file was downloaded correctly.
It is highly recommended that the upgrade be performed using the web-based cluster management interface known as the management GUI. Instructions are available for performing a CCU in IBM Knowledge Center. Search for 'IBM FlashSystem V9000,' then navigate to Upgrading the system. Included is information on retrieving software packages, using the update test utility, and automatically updating using either the GUI or the CLI.
If the upgrade takes more than two hours to complete, it may have stalled. Upgrade status is viewed by issuing lsupdate CLI command or by going to Settings --> System --> Update System in the GUI.Both show a 'Stalled' status. In most cases, this can be resolved by aborting the upgrade and reattempting the upgrade after the system downgrades to its original level.To abort the upgrade, issue the applysoftware -abort CLI command or click the 'Stop Upgrade' button in the GUI.
You may get a battery or quorum alert during upgrade due to required reconfiguration. These alerts should be automatically cleared when the upgrade is completed. They may be visible from the Events view of the management GUI if the filter is set to 'Show All,' but they should no longer appear in the Recommended Actions, Unfixed Messages, or Alerts views. If you see unfixed battery or quorum alerts after an upgrade is complete, contact IBM Support.
If you suspect a hardware failure, issue the lsupdate command to confirm the state of your system. This command shows that the system is in a hardware_failed state and the event log contains a 'System upgrade suspended' event. You may resume the upgrade by issuing the applysoftware -resume -force command for the following conditions:
If the upgrade cannot be resumed or you have other alerts which cannot be cleared, contact IBM Support.The battery reconditioning feature calibrates the gauge that reports the amount of charge on the batteries.On systems that have been installed for 10 months or more or systems that have experienced several power outages, the recommendation to run 'battery reconditioning' will appear in the event log shortly after upgrading.This is normal. Use the management GUI to run a DMP for this error or see the FlashSystem Knowledge Center to view how to properly issue the chenclosureslot command in reference to this issue.Use the following link to access the Knowledge Center page for battery reconditioning.
