iv IBM Hyper-Scale Manager

Overview

IBM® Hyper-Scale Manager is the official "A-line" hybrid cloud managementapplication, supporting all-flash, disk and software-defined storage (SDS) systems.IBM Hyper-Scale Manager allows for unified management across the IBMFlashSystem A9000 and A9000R, IBM XIV Gen3 and IBM Spectrum Accelerate(on/off premises) family.

IBM Hyper-Scale Manager reduces operational complexity and enhances capacityplanning through integrated management for large storage system deployments.Storage administrators can log in to the IBM Hyper-Scale Manager and use itsadvanced web-based user interface (UI) for managing and monitoring multiplestorage systems.

Automation and control of IBM Hyper-Scale Manager can be implemented throughits Representational State Transfer (REST) application programming interfaces(APIs).

Note: IBM XIV® and IBM Spectrum Accelerate™ systems cannot be managed withIBM Hyper-Scale Manager versions previous to 5.1.x. For these systems, use IBMXIV Management Tools version 4.8 or migrate your system inventory to the newestversion of IBM Hyper-Scale Manager. For more information, see "Migrating IBMHyper-Scale Manager inventory from version 4.x" in the IBM Hyper-Scale Managerversion 5.1 User Guide (SC27-8560-03).

The IBM Hyper-Scale Manager software package can be downloaded at any timefrom the IBM Fix Central website (www.ibm.com/support/fixcentral). For moreinformation about IBM Hyper-Scale Manager, see Related information andpublications.

Refer to the IBM Spectrum AcceleratePlanning, Deployment, and Operation Guide (SC27-6695) for further information ondeploying IBM Spectrum Accelerate.

LimitationsThe following functional limitations apply to IBM Hyper-Scale Manager version 5.1and may remain in effect in future software versions.v IBM Hyper-Scale Manager 5.0 requires a clean installation and cannot be

installed as an upgrade of previous IBM Hyper-Scale Manager or IBM XIVManagement Tools versions. See the IBM Hyper-Scale Manager version 5.1 UserGuide (SC27-8560-03) for information on how to migrate your existing systemsinventory from version 4.x to the newly installed IBM Hyper-Scale Manager.

v The following functions are available only through the stand-alone XCLI utilitythat is bundled in IBM Hyper-Scale Manager 5.0.x:– LDAP configuration– IP interface

Overview 9

The XCLI utility needs to be installed separately.

Known issuesFollowing are the known issues in IBM Hyper-Scale Manager version 5.1, alongwith possible solutions or workarounds (if available).

Ticket ID Description

PUI-10355 A system in the Hyper-Scale Manager inventory isn't displayed when an incorrecttimezone is defined on that specific system.

Workaround: Configure a valid time zone on the system using the timezone_set CLIcommand. A list of valid time zones can be retrieved using the timezone_listcommand.

PUI-10093 Three-way mirroring is not supported.

Workaround: No workaround is currently available.

PUI-9903 Creating a mirror fails because the source Volume has a "last replicated" Snapshotfrom a previously created mirroring relation.

Workaround: Delete the last replicated snapshot.

PUI-9866 Can't delete a Domain that once had an asynchronous mirror because the schedulerstill exists.

Workaround: Use the domain_detach_object CLI command to detach the schedulefrom the Domain and delete the Domain.

PUI-9429 There is no upgrade path from IBM Hyper-Scale Manager version 4.x to version 5.x.See the IBM Hyper-Scale Manager version 5.1 User Guide (SC27-8560-03) for informationon how to migrate your existing systems inventory from version 4.x to the newlyinstalled IBM Hyper-Scale Manager.

Workaround: No workaround is currently available.

PUI-9034 Adding a mirrored Volume to a mirrored Consistency Group won't work if the remotesystem is not monitored, since the RPO and schedule of the remote mirroredConsistency Group are unavailable.

PUI-8963 Changing the RPO for a mirror whose Volumes reside in different Domains fails.

PUI-8907 When you change the RPO for an asynchronous mirror, the interval is updated onlyon the source system if the destination system is not monitored.

PUI-8861 When mirroring multiple Volumes, the remote System field is marked as "Notmonitored".

Workaround: No workaround is currently available.

PUI-8858 Creating a mirror in mass configuration fails when the Volumes aren't in the sameDomain.

PUI-8840 If the login user is not defined on the destination system when you Create Mirror, thedestination Domain/Pool fields are empty.

Workaround: Define the login user on both the source and destination systems.

10 IBM Hyper-Scale Manager

Ticket ID Description

PUI-8834 A system error is displayed during Create Mirror when the Volume belongs to aDomain but the target does not.

Workaround: No workaround is currently available.

PUI-8808 When Capacity statistics data is collected over a 3-day interval (the minimum numberof days for collecting data for Capacity graphs), the graphs with the forecast are notshown.

Workaround: No workaround is currently available.

PUI-8750 The last data point on the Capacity statistics forecast graph is greater than theSystem's physical size.

Workaround: No workaround is currently available.

PUI-8735 The Capacity statistics interval between the first date of the historical data displayedand the last date of the forecast data displayed is not accurate.

Workaround: No workaround is currently available.

PUI-8592 When you select Last Month as the Range on a Capacity statistics graph, the first dayof the month is not displayed on the x-axis.

Workaround: The tooltip for this day displays the correct data.

PUI-8560 The Host and LUN dialog box in the Volume Mapping form does not close whenyou click on the "x".

Workaround: Select Cluster in the capsule before clicking Create Mapping.

PUI-8455 The Change Role and Switch Role mirroring actions are not available in massconfigurations.

Workaround: No workaround is currently available.

PUI-7609 The System status alert panel does not update its status from Unprotected-Rebuilding,but remains Unprotected.
