------------------------------------------------------------------------------- Software name IBM Storwize V7000 for Lenovo Controller Firmware Update Bundle Supported Model System name IBM Storwize V7000 for Lenovo Version 8.1.1.2 Issue date May 11, 2018 Prerequisites: None ------------------------------------------------------------------------------- WHAT THIS PACKAGE DOES ------------------------------------------------------------------------------- This firmware update enables you to update the controller firmware via; 1. IBM Storwize V7000 for Lenovo - Web User Interface. 2. IBM Storwize V7000 for Lenovo - Command Line Interface (CLI). ------------------------------------------------------------------------------- Version history ------------------------------------------------------------------------------- The following versions of Controller Firmware that been released to date. Summary of Changes Where: < > Package version [Important] Important update (New) New function or enhancement (Fix) Correction to existing function - [Important] The following issues have been resolved with this release: An issue in the handling of compressed volume shrink operations, in the presence of Easy Tier migrations, can cause DRAID mdisk timeouts leading to an offline mdisk group (HU01720) - EasyTier, Compression Reads of 4K/8K from an array can under exceptional circumstances return invalid data (HU01767) - RAID, Thin Provisioning A SCSI UNMAP issue can cause repeated node warmstarts (HU01769) - Distributed RAID When a DRAID array has multiple drive failures and the number of failed drives is greater than the number of rebuild areas in the array it is possible that the storage pool will be taken offline during the copyback phase of a rebuild (HU01792) - Distributed RAID An issue with the CMOS battery in a node can cause an unexpectedly large log file to be generated by the BMC. At log collection the node may be taken offline (HU01771) - System Monitoring - (Fix) The following issues have been resolved with this release: A misreading of the PSU register can lead to failure events being logged incorrectly (HU01619) - System Monitoring A timing window issue, during an upgrade, can cause the node restarting to warmstart, stalling the upgrade (HU01664) - System Update The timeout setting for key server commands may be too brief, when the server is busy, causing those commands to fail (HU01740) - Encryption A scheduling issue may cause a config node warmstart (HU01756) - [Important] The following issues have been resolved with this release: An issue in the handling of GUI certificates may cause warmstarts leading to a T2 recovery (IT19192) - Graphical User Interface, Reliability Availability Serviceability For large drive sizes the DRAID rebuild process can consume significant CPU resource adversely impacting system performance (IT23747) - Distributed RAID - (Fix) The following issues have been resolved with this release: The algorithm used to calculate an SSD"s replacement date can sometimes produce incorrect results leading to a premature End-of-Life error being reported (HU01655) - Drives - (New) The following new features have been introduced in this release: Spectrum Virtualize for Public Cloud Thin-Provisioned Mdisks Port Grouping and Scalability for iSCSI Allow username for iSCSI host attach authentication - [Important] The following issues have been resolved with this release: A slow raid member drive, in a mdisk, may cause node warmstarts and the mdisk to go offline for a short time (HU01726) - RAID When using the charraymember CLI command if a member id is entered that is greater than the maximum number of members in a TRAID array then a T2 recovery will be initiated (HU01618) - RAID Configuration changes can slow critical processes and if this coincides with cloud account statistical data being adjusted a T2 may occur (HU01620) - Transparent Cloud Tiering Metadata between two nodes in an IO group can become out of step leaving one node unaware of work scheduled on its partner. This can lead to stuck array synchronisation and false 1691 events (HU01671) - RAID Entering an invalid parameter in the addvdiskaccess command may initiate a T2 recovery (HU01678) - Command Line Interface An issue in DRAID can cause repeated node warmstarts in the circumstances of a degraded copyback operation to a drive (HU01420) - Distributed RAID During an upgrade a resource locking issue in the compression component can cause a node to warmstart multiple times and become unavailable (HU01525) - Compression, System Update A congested fabric causes the Fibre Channel adapter firmware to abort IO resulting in node warmstarts (HU01632) - Reliability Availability Serviceability - (Fix) The following issues have been resolved with this release: Where a controller, which has been assigned to a specific site, has some logins intentionally removed then the system can continue to display the controller as degraded even when the DMP has been followed and errors fixed (HU01190) - Backend Storage During a DRAID Mdisk copy-back operation a miscalculation of the remaining work may cause a node warmstart (HU01512) - Distributed RAID Where multiple syslog server IPs are entered in rapid succession the mksyslogserver command may not include them all in the syslog.conf file (HU01559) - System Monitoring When security scanners send garbage data to SVC/Storwize iSCSI target addresses a node warmstart may occur (HU01602) - iSCSI Even though synchronisation has completed a RAID array may stilll show progress to be at 99% (HU01633) - RAID There may be a node warmstart when a switch of direction, in a HyperSwap relationship, fails to complete properly (HU01654) - HyperSwap Due to an issue in Lancer G5 firmware after a node reboot the LED of the 10GBE port may remain amber even though the port is working normally (IT20586) - Reliability Availability Serviceability ------------------------------------------------------------------------------- Limitations and considerations ------------------------------------------------------------------------------- Customers with Storwize V7000 Gen 2 Model 6195 systems should not upgrade to v8.1.1.0 or later. This is a temporary restriction that will be lifted in a future PTF. ------------------------------------------------------------------------------- Enhanced Call Home should not be used on systems running v8.1.1.0 or later. This is a temporary restriction that will be lifted in a future PTF. ------------------------------------------------------------------------------- ----------------------------------------------------------------------------- TRADEMARKS ----------------------------------------------------------------------------- * The following are registered trademarks of Lenovo.
