5 Release Notes These Release Notes are for IBM XIV Gen3 Storage System Version Release date 6 June 2014 What's new in IBM XIV software version Availability of code load IBM XIV software version for IBM XIV Storage System Gen3 delivers the following: v Bug fixes v New Cloud license Hardware Version a is only available for Gen3 hardware. Software This version supports hot upgrade from: v b v a v v b v v a v v c v b v a v v b Technician Assistant Tool The upgrade requires Technician Assistant (TA) Tool version 4.8.5, or above. Documentation Refer to Preparing for code load on the Information Center. This topic details the steps required from the customer in order to prepare for the code load. com.ibm.help.xiv.doc/xiv_po_11_1_02.html Availability of Host Attachment Kits (HAK) IBM XIV Host Attachment Kit The latest IBM XIV Host Attachment Kit (HAK) version can be downloaded from the IBM Fix Central website: support/fixcentral Copyright IBM Corp

6 IBM Storage Host Software Solutions Information Center For detailed usage information, refer to the IBM Storage Host Software Solutions Information Center: strhosts/ic. Limitations 1. IBM Hyper-Scale Mobility applies to systems located within the same data center. 2. Using Hyper-Scale Mobility to mobilize volumes that are mapped to Unix or Linux hosts, and are backed-up using IBM Tivoli Storage FlashCopy Manager version 3.2 or earlier, is not supported. 3. IBM Hyper-Scale Mobility cannot be applied directly on a volume that belongs to a consistency group. Before such a volume can be moved using IBM Hyper-Scale Mobility, it must be removed from the consistency group. 4. IBM Hyper-Scale Mobility does not apply to volume snapshots. When the migration is changed to proxy state, all snapshots of the pertinent migrated volume are deleted automatically. 5. IBM Hyper-Scale Mobility does not migrate a volume that is in a mirroring relationships. Before a volume can be moved using IBM Hyper-Scale Mobility, its mirroring relationship must be deleted. 6. Using Hyper-Scale Mobility to mobilize volumes that are mapped to Windows Server hosts, and are backed-up using Microsoft Volume Shadow Copy Service, with IBM XIV Provider for Microsoft Windows Volume Shadow Copy Service (VSS) version or earlier, is not supported. To use Hyper-Scale Mobility in this case, IBM XIV Provider for Microsoft Windows Volume Shadow Copy Service (VSS) version or later must be installed. Note: IBM Tivoli Storage FlashCopy Manager for Windows is relying on Microsoft Volume Shadow Copy Service. To use Hyper-Scale Mobility with IBM Tivoli Storage FlashCopy Manager for Windows, IBM XIV Provider for Microsoft Windows Volume Shadow Copy Service (VSS) version or later must be installed. 7. Using Hyper-Scale Mobility to mobilize volumes that are mapped to Windows Server hosts, and are protected by IBM Storage Enabler for Windows Failover Clustering version or earlier, is not supported. To use Hyper-Scale Mobility in this case, IBM Storage Enabler for Windows Failover Clustering version or later must be installed. Additional information may be available from the respective release notes of the products mentioned in the limitations: 1. For IBM Tivoli Storage FlashCopy Manager for Unix and Linux please refer to release notes of version 4.1 or later. 2. For IBM XIV Provider for Microsoft Windows Volume Shadow Copy Service release notes, please refer to: topic/com.ibm.help.strghosts.doc/vss-homepage.html. 3. For IBM Storage Enabler for Windows Failover Clustering, release notes, please refer to: %2Fcom.ibm.help.strghosts.doc%2Fmscs-homepage.html. 2 IBM XIV Gen3 Storage System: Release Notes for version

7 Fixed issues SYS A firewall between XIV and the Tivoli Key Lifecycle Manager (TKLM) server needs to allow an Internet Control Message Protocol (ICMP) ping for XIV to connect to the TKLM server. Service and up SYS In rare conditions, data on a remote mirrored volume may become inconsistent with the data on the source volume. The conditions are: The source volume has been copied from another volume using XIV command VOL_COPY; the background copy is still in progress; and the source volume has at least one snapshot, while a write operation is done on a partition that has not been copied yet to the source volume, at a particular timing. The inconsistency will be automatically detected later by the XIV scrub process and trigger an event, requiring XIV support. The inconsistency will be fixed by XIV support. High Impact and up SYS There is a low probability that the host may lose connectivity to the XIV storage due to faulty behavior of the XIV HBA. High Impact and up SYS The following new behaviour is not documented on the XCLI Reference Guide. Starting from release a, application administrators can execute the following commands: v mirror_list v schedule_list v sync_job_list Service a Release Notes 3

8 SYS During Data Migration, an internal process failure might cause the system to lose the disks on the module. This situation might arise, in rare cases, when all of the following occur: v There are multiple reads or writes directed to a specific partition that has not yet been migrated to XIV. v Serving data from the migration source is extremely slow. v There is a hardware failure (disk/module). High Impact and up SYS If an encrypted system is powered on when the Tivoli Key Lifecycle Manager (TKLM) server is not available, the system will stay in maintenance mode. The system cannot be moved to the ON state without the involvement of support. Fix description: A new command encrypt_recovery_finish has been added in order to move the system state to ON. The command can be used once connectivity between XIV and the TKLM server is available, and there are no other XIV maintenance issues. The command is documented in the IBM XIV Storage System XCLI Reference Guide. High Impact and up SYS The events FC_LINK_IS_NOW_DOWN and FC_LINK_IS_NOW_UP are not visible to external users. Service and up SYS In rare conditions, access of a host to a volume that is the source of a disconnected mirror, may be lost when the host is sending a space reclamation SCSI command. High impact and up SYS This release of XIV microcode addresses the CVE "Heartbleed" issue ( 4 IBM XIV Gen3 Storage System: Release Notes for version

9 After upgrading from a version exposed to Heartbleed, additional steps are required: 1. The digital SSL Certificates provided by IBM need to be replaced, and will be replaced by IBM as part of the upgrade procedure. 2. If you installed your own digital certificates, revoke those and replace them with new certificates. Be sure not to generate the new certificates using the old private key and create a new private key (using openssl genrsa). Use the new private key to create the new certificate signing request (CSR). 3. The admin password needs to be changed, as well as any additional users defined internally (if you're using LDAP authentication, then only the admin password needs to be changed). Make sure to do this after upgrading and replacing the digital certificates. Hyper Affected version(s): , a, , , a Known issues Copyrights SYS After 4377 Hyper-Scale Mobility migrations, the maximum number of volumes in a system (12,000) will decrease by 1 volume with each new migration. Moderate and up SYS iscsi Login using the CHAP protocol fails.
