IBM XIV Host Attachment Kit v.1.6 for AIX,SLES,HP-UX,RHEL,Windows,Solaris released

IBM XIV Host Attachment Kit for AIX, Version 1.6

The IBM XIV Host Attachment Kit (HAK) for AIX is a software pack that simplifies the task of connecting an IBM AIX host to the IBM XIV Storage System. The HAK provides a set of CLI-based tools that automatically detect any physically connected XIV storage system (single system or an array), define the host on the XIV storage system, and apply best-practice native AIX multipath configuration. After the connection is established, XIV-based storage volumes can be mapped to the host without any additional manual configuration, and can be accessed and used from the host for a range of storage operations.

IBM XIV Host Attachment Kit for SLES, Version 1.6

The IBM XIV Host Attachment Kit (HAK) for SLES is a software pack that simplifies the task of connecting an SLES host to the IBM XIV Storage System. The HAK provides a set of CLI-based tools that automatically detect any physically connected XIV storage system (single system or an array), define the host on the XIV storage system, and apply best-practice native SLES multipath configuration. After the connection is established, XIV-based storage volumes can be mapped to the host without any additional manual configuration, and can be accessed and used from the host for a range of storage operations.

IBM XIV Host Attachment Kit for HP-UX, Version 1.6

The IBM XIV Host Attachment Kit (HAK) for HP-UX is a software pack that simplifies the task of connecting an HP-UX host to the IBM XIV Storage System. The HAK provides a set of CLI-based tools that automatically detect any physically connected XIV storage system (single system or an array), define the host on the XIV storage system, and apply best-practice native HP-UX multipath configuration. After the connection is established, XIV-based storage volumes can be mapped to the host without any additional manual configuration, and can be accessed and used from the host for a range of storage operations.

IBM XIV Host Attachment Kit for RHEL, Version 1.6

The IBM XIV Host Attachment Kit (HAK) for RHEL is a software pack that simplifies the task of connecting a RHEL host to the IBM XIV Storage System. The HAK provides a set of CLI-based tools that automatically detect any physically connected XIV storage system (single system or an array), define the host on the XIV storage system, and apply best-practice native RHEL multipath configuration. After the connection is established, XIV-based storage volumes can be mapped to the host without any additional manual configuration, and can be accessed and used from the host for a range of storage operations.

IBM XIV Host Attachment Kit for Windows, Version 1.6

The IBM XIV Host Attachment Kit (HAK) for Windows is a software pack that simplifies the task of connecting a Microsoft Windows Server host to the IBM XIV Storage System. The HAK provides a set of CLI-based tools that automatically detect any physically connected XIV storage system (single system or an array), define the host on the XIV storage system, and apply best-practice native Windows Server multipath configuration. To further help the administrator, the HAK also installs required Windows Server hotfixes, and checks the compatibility of the installed HBA drivers as it was known when this HAK was released. After the connection is established, XIV-based storage volumes can be mapped to the host without any additional manual configuration, and can be accessed and used from the host for a range of storage operations.

IBM XIV Host Attachment Kit for Solaris, Version 1.6

The IBM XIV Host Attachment Kit (HAK) for Solaris is a software pack that simplifies the task of connecting an Solaris host to the IBM XIV Storage System. The HAK provides a set of CLI-based tools that automatically detect any physically connected XIV storage system (single system or an array), define the host on the XIV storage system, and apply best-practice native Solaris multipath configuration. After the connection is established, XIV-based storage volumes can be mapped to the host without any additional manual configuration, and can be accessed and used from the host for a range of storage operations.

Potential Problem on XIV Storage System microcode versions 10.2.2 thru 10.2.4.a

Potential Problem on XIV Storage System ranging microcode versions from 10.2.2 thru 10.2.4.a that can be caused by changing system time via Network Time Protocol (NTP) or when changing the clock via XCLI

When the system time is changed to more than ~500 years ahead in the future, the Manager Node will get stuck. It will stop handling xcli operations, but more severely – it will not be able to detect any failure in the system. Once such a failure occurs, all hosts will lose access to the system and IBM support needs to be contacted immediately.

In case of a Manager Node impact, the system will continue to serve I/O’s but in case of a subsequent data component failure (either a disk or a module) the system might not properly identify the failure and therefore will not initiate a rebuild process and possibly cause hosts to lose access to data. Other symptoms may include, but not limited to: the XIV will not be able to properly detect loss of input AC (building power outage) and therefore shutdown while ensuring all writes are committed to disk; the customer may not be able perform any operations on the XIV, including GUI updates or inquiries.

If the machine is reporting to the XIV service center then XIV will receive the proper events that will notify us regarding this issue and we will be able to contact the customer and verify/fix this state.

 

Environment

Affected versions Environment

  • 10.2.2
  • 10.2.2.a
  • 10.2.4
  • 10.2.4.a

Resolving the problem

Mitigation

  • Remove NTP server configuration from the XIV to avoid getting into this situation.
  • Do not perform a manual change of the machine time to a date 500 years or more in the future (this would only happen by an error).

Fix
Fix is included in version 10.2.4.b version that is planned to be released in Q2 2011.

  • 10.2.4.b version will disallow setting of invalid dates
  • Year must be between 2000 and 2030,
  • 10.2.4.b will have error handling messages and more debug information to better manage this situation.
  • NEW_TIME_CHANGE_IS_INAVLID
    This event will be raised when an attempt to set the time is blocked because time is invalid. (year not between 2000 to 2030)
  • SETTING_NEW_TIME
    This event is raised every time an attempt to set a ‘complete’ time, not a delta from the last time setting. (when delta >TIME_UPDATE_MINIMUM_DIFF)
  • Both events are limited to one in an hour.

IBM XIV Storage Plug-in for Microsoft Cluster Server (MSCS), Version 1.0.2.1

The plug-in enables failover automation of XIV storage services that run on two geographically dispersed cluster nodes, enabling deployment of MSCS in a geo-cluster configuration.

 

MSCS and the XIV storage system support one-button fail over initiation for automated recovery, or manual fail over for step-by-step control over the recovery process. Both accommodate a broad range of fail over scenarios and infrastructure components. Version 1.0.2.1 includes a hotfix for a known issue.

To avoid potential loss of access, customers must be on "IBM XIV Host Attachment Kit for Windows, Version 1.5.3" or above

To avoid potential loss of access that might happen during XIV operation or hot upgrade customers must be on “IBM XIV Host Attachment Kit for Windows, Version 1.5.3” or above and before the upgrade

Symptom

Servers disconnect from XIV

Cause

  1. During some cases of module failure (e.g. SMI timeout) Windows 2003 server might disconnect from XIV
  2. During XIV hot upgrade Windows 2003 server might disconnect from XIV
  3. Extreme steady state situations

 

Environment

Windows 2003 or Windows 2003 R2 in a cluster environment connected to XIV

 

Resolving the problem

In a Windows 2003 or Windows 2003 R2 in a cluster environment, customers must be on “IBM XIV Host Attachment Kit for Windows, Version 1.5.3” or above.

This release of “IBM XIV Host Attachment Kit for Windows, Version 1.5.3” contains a fix to avoid potential loss of access.
Here is the link to download “IBM XIV Host Attachment Kit for Windows, Version 1.5.3” :
