Preventive Service Planning
Abstract
This document lists the configuration limits and restrictions specific to IBM Storwize V5000, V5010, V5020 and V5030 software version 7.6.x
Content
V5010, V5020 and V5030 are supported at version 7.6.1.0 and higher
The use of WAN optimization devices such as Riverbed is not supported in native Ethernet IP partnership configurations containing Storwize V5000.
DRAID Strip Size
For candidate drives, with a capacity greater than 4TB, a strip size of 128 cannot be specified for either RAID-5 or RAID-6 DRAID arrays. For these drives a strip size of 256 should be used.
Quorum restriction with version 7.6.1.0
Customers are advised not to force stop and then immediately restart multiple quorum applications in quick succession (e.g. with CTRL+C followed by starting the applications again), especially when using three or more quorum applications. This action may cause the Storwize cluster nodes to restart. Customers are advised to wait a minimum of one minute between restarting each quorum application instance.
This restriction will be removed in a future release of V5000 Software.
Applying drive software update to all drives in a system with a distributed array containing more than 16 drives
Please do not update drive software on all drives together in a system that has a distributed array with more than 16 drives.
The following will perform a drive software upgrade on all drives together and are restricted in this case:
- Using command applydrivesoftware with "-all" parameter.
- Using the "Upgrade All" option in the GUI under "Pools > Internal Storage > Actions".
To workaround this restriction, please perform drive software update on one drive at a time.
You can do this using command applydrivesoftware with "-drive" parameter for each drive.
This restriction is now resolved with software version of 7.6.0.4
iSCSI Limitations
iSCSI host attachment is currently not supported with Software Version 7.6
This restriction is now resolved and iSCSI host attachment is supported with software version 7.6.0.2 and higher.
Due to the requirement for multiple access IO groups, iSCSI attached host types are not supported with HyperSwap volumes.
HyperSwap
HyperSwap is not supported with Software Version version 7.6.0
This restriction is now resolved and HyperSwap is supported with software version 7.6.0.1 and higher.
When using the HyperSwap function with software version 7.6.0.1 and higher, please configure your host multipath driver to use an ALUA-based path policy.
Due to the requirement for multiple access IO groups, iSCSI and SAS attached host types are not supported with HyperSwap volumes.
AIX Live Partition Mobility (LPM)
AIX LPM is now supported with the HyperSwap function and AIX 7.x
New CLI Commands
The following new CLI commands are not currently supported on Software Version 7.6
* addvolumecopy
* rmvolumecopy
Attempting to use a feature which is not supported will return the following error:
CMMVC7205E The command failed because it is not supported.
Support for these commands will be enabled in a future software release.
Clustered Systems
A Storwize V5000 system at version 7.6 and higher requires native Fibre Channel SAN or alternatively 8Gbps/16Gbps Direct Attach Fibre Channel connectivity for communication between all nodes in the local cluster. Fibre Channel over Ethernet ( FCoE ) connectivity for communication between all nodes in the local cluster is also supported.
Partnerships between systems for Metro Mirror or Global Mirror replication can be used with both Fibre Channel, Native Ethernet connectivity and FCoE connectivity, however direct FCoE links are only supported to a maximum of 300 metres. Distances greater than 300 metres are only supported when using an FCIP link or Fibre Channel between source and target.
Direct Attachment
For information on support configurations using direct attachment please visit the following document
Direct Attachment of Storwize and SAN Volume Controller Systems
16Gbps Fibre Channel Canister Connection
Please see SSIC for supported 16Gbps Fibre Channel configurations supported with 16Gbps node hardware. Note 16Gbps Node hardware is supported when connected to Brocade and Cisco 8Gbps or 16Gbps fabrics only. Direct connections to 2Gbps or 4Gbps SAN or direct host attachment to 2Gbps or 4Gbps ports is not supported. Other configured switches which are not directly connected to the16Gbps Node hardware can be any supported fabric switch as currently listed in SSIC.
IP Partnership
Using an Ethernet Switch to convert a 10Gbps IP partnership link to 1Gbps link and vice versa is not supported. Therefore, the IP infrastructure on the two partnership sites should both be 1Gbps or 10Gbps. However, bandwidth limiting on 10Gbps and 1Gbps IP partnership between sites is supported.
Fabric Limitation
Only one FCF ( Fibre Channel Forwarder ) switch per fabric is supported.
VMware vSphere Virtual Volumes (VVols)
The maximum number of Virtual Machines on a single VMware ESXi host in a Storwize / VVol storage configuration is limited to 680.
The use of VMware vSphere Virtual Volumes (VVols) on a system that is configured for HyperSwap is not currently supported with SVC/Storwize.
DS4000 Maintenance
Storwize V5000 supports concurrent ESM firmware upgrades for those DS4000 models listed as such on the Supported Hardware List when they are running either 06.23.05.00 or later controller firmware. However, controllers running firmware levels earlier than 06.23.05.00 will not be supported for concurrent ESM upgrades. Customers in this situation, who wish to gain support for concurrent ESM upgrades, will need to first upgrade the DS4000 controller firmware level to 06.23.05.00. This action is a controller firmware upgrade, not an ESM upgrade and concurrent controller firmware upgrades are already supported in conjunction with Storwize V5000. Once the controller firmware is at 06.23.05.00 or later the ESM firmware can be upgraded concurrently.
Note: The DS4000 ESM firmware upgrade must be done on one disk expansion enclosure at a time. A 10 minute delay from when one enclosure is upgraded to the start of the upgrade of another enclosure is required. Confirm via the Storage Manager applications "Recovery Guru" that the DS4000 status is in an optimal state before upgrading the next enclosure. If it is not, then do not continue ESM firmware upgrades until the problem is resolved.
Host Limitations
Microsoft Offload Data Transfer ( ODX ) and SDDDSM Requirements
Storwize V5000 version 7.5.0 introduced support for Microsft ODX. In order to utilise this function all windows hosts accessing Storwize V5000 are required to be at a minimum SDDDSM version of 2.4.5.0. Earlier versions of SDDDSM are not supported when the ODX function is activated.
Windows NTP server
The Linux NTP client used by Storwize V5000 may not always function correctly with Windows W32Time NTP Server
TPC Restrictions
TPC Supported Versions
The minimum supported TPC version for SVC/Storwize version 7.6 is TPC 5.2.6.
Vdisk Migration
When a vdisk is migrated between a child pool and its parent, or between child pools of the same parent, it is necessary to re-probe the cluster from TPC as no event is logged on the cluster for this type of migration
Migrations between non-child pools also currently require a re-probe
These issues will be addressed in future releases of TPC and SVC/Storwize Code.
Oracle
Restriction 1: For RHEL4 set Oracle Clusterware 'misscount' parameter to a bigger one to allow SDD to do path failover first. The default miscount setting 60s is too short for SDD. We recommend to set it 90s or 120s. Command to use: crsctl set css misscount 90
Priority Flow Control for iSCSI
Priority Flow Control for iSCSI is supported on Brocade VDX 10-gigabit Ethernet switches only.
SCSI LUN ID 0
SAS Hosts running Linux or Vmware operating systems.
Removal of LUN's mapped to SCSI ID 0 is not supported and may result in a loss of access to the remaining LUNs
Maximum Configurations
Configuration limits for Storwize V5000:
Maximum WWPNs per host Object and iSCSI Names
The maximum number of FC/SAS/FCoE hosts ports supported per host object is 32.
The maximum number of iSCSI names supported per host object is 8.
Please see the following document
http://www-01.ibm.com/support/docview.wss?uid=ssg1S1005261
