Veritas InfoScale 7.0: Configuring I/O fencing
I/O fencing protects the data on shared disks when nodes in a cluster detect a change in the cluster membership that indicates a split-brain condition. In a partitioned cluster, a split-brain condition occurs where one side of the partition thinks the other side is down and takes over its resources. When you install Veritas InfoScale Enterprise, the installer installs the I/O fencing driver, which is part of the VRTSvxfen package. After you install and configure the product, you must configure I/O fencing so that it can protect your data on shared disks. You can configure disk-based I/O fencing, server-based I/O fencing, or majority-based I/O fencing. Before you configure I/O fencing, make sure that you meet the I/O fencing requirements. After you meet the requirements, you can refer to About planning to configure I/O fencing to perform the preparatory tasks and then configure I/O fencing. For more details about I/O fencing configuration, see: Cluster Server Configuration and Upgrade Guide Veritas InfoScale documentation for other releases andplatforms can be found on the SORT website.

SFHA Solutions 6.0.1: Using vxcdsconvert to make Veritas Volume Manager (VxVM) disks and disk groups portable between systems for Cross-platform Data Sharing (CDS)
The vxcdsconvert command makes disks and disk groups portable between systems running VxVM with the Cross-platform Data Sharing (CDS) feature. For more information on the CDS feature, see: Overview of the CDS feature Setting up your system to use CDS You can resize the CDS disks to larger than 1 TB. For more information, see: Dynamic LUN expansion You can use the vxcdsconvert command to: Check whether disks and disk groups can be made portable (using the –A option). Convert disks and disk groups to be CDS-compatible. For more information on the conversion procedure, see: Converting non-CDS disks to CDS disks Converting a non-CDS disk group to a CDS disk group Note the following points: The vxcdsconvert command requires that disk groups be version 110 or greater. When a disk group is made portable, all disks within the disk group are also converted. Converting a disk group that contains RAID-5 volumes and logs fails, if there is insufficient space in the disk group to create an additional temporary RAID-5 log. The default private region size increased from 512 KB to 1 MB in SFHA release 3.2, and from 1 MB to 32 MB in release 5.0. vxcdsconvert (1M) 6.0.1 manual pages: AIX HP-UX Linux Solaris VxVM documentation for other platforms and releases can be found on the SORT website.
SFHA Solutions 6.0.1: Maximizing storage utilization using thin provisioning
Thin provisioning helps you save SAN/NAS storage space. In thin provisioning, instead of provisioning full storage space to a user, the thin provisioning software allocates disk space in a flexible manner based on the minimum space that is required by each user at the given time. Thin provisioning saves considerable storage space in contrast with the conventional storage, where storage is allocated beyond the current requirements of the application. For more information on the advantages of using thin provisioning, refer to: Why Thin Provisioning and Thin Reclamation? Thin provisioning - addressing the problems with over allocation How does Veritas Operations Manager help you reclaim underutilized storage? Veritas Operations Manager offers different solutions for using thin provisioning and thin reclamation. These solutions are listed below: Thin Provisioning Reclamation Add-on You can use the Thin Provisioning Reclamation Add-on to optimize storage space by using Veritas File System (VxFS) thin capabilities and Storage Foundation Thin Reclamation API. You can run thin reclamation on the following objects in Veritas Operations Manager: Storage array: Select thin pools or LUNs in the context of an array. Business entity: Specify a flexible reclamation boundary based on a business entity. Since a business entity can include many objects and is inherently dynamic, the LUNs that are reclaimed change automatically whenever changes occur within that business entity. Hosts: Select multiple file systems in context of the hosts. The associated LUNs are reclaimed. You can configure thin reclamation processes to run at regular scheduled intervals. If you have not scheduled the process run, you can also run it manually. For more information about configuring and running the Thin Provisioning Reclamation Add-on, see: Veritas Operations Manager Thin Provisioning Reclamation Add-on Configuring a thin reclamation process for an array Configuring a thin reclamation process for a business entity Configuring a thin reclamation process for host Running reclamation processes manually Veritas Storage Foundation Add-on for Storage Provisioning You can use the Storage Foundation Add-on for Storage Provisioning to migrate the volume from thick to thin Logical Unit Number (LUN). Using this add-on, you can select a specific volume to migrate, and optionally change its layout before migration. For more information on using the Storage Foundation Add-on for Storage Provisioning, see: Moving volumes from thick to thin LUNs Impact Analysis report Veritas Operations Manager policy checks Veritas Operations Manager policy check feature uses individual rules to validate if the datacenter configuration conforms to a pre-defined standard. You can create policy templates to check the performance, availability, and utilization of the storage objects in your datacenter. For more information on policy checks, see: About policy checks Storage reclamation and thin provisioning reports Veritas Operations Manager provides extensive reporting capabilities centered around Storage Foundation and High Availability products. It includes reports related to storage utilization, storage reclamation, and inventory. For more information on thin provisioning reports, see: Storage reclamation and thin provisioning reports For more information about Storage Foundation thin reclamation and thin provisioning features, see: Veritas Storage Foundation Administrator’s Guide Veritas Storage Foundation and High Availability Solutions 6.0.1 Solutions Guide Storage Foundation and High Availability and Veritas Operations Manager documentation for other releases and platforms can be found on the SORT website.Welcome to the Veritas Relisiency Platform Forum - Join the Conversation!
