M but about half of the VTVs will have become unavailable for recall back into the VSM buffer In the event of a failure in a two LSM single ACS configuration VTCS will usually be able to continue migration again since there should be available MVCs in each LSM but about half of the VTVs will have become unavailable even with duplexed VTVs This is true because VTCS only guarantees that the two VTV copies will be on separate MVCs regardless of location in the libraries Named MVCPools in each LSM does not completely address this issue because the MVCs can still be moved from one LSM to the other depending on RTD allocation In a two LSM multi ACS environment with duplexed triplexed or quadplexed VTVs the customer would eliminate the exposure of a VTV being unavailable due to an LSM or ACS failure by migrating one VTV copy to each ACS using MIGpol or ACS list for duplexed only Migrations and recalls would continue to occur in the event of an ACS failure or media failure and will result in business continuity in the event the local site is destroyed B Considering VTCS Maintenance Customers should ensure that they have all of the latest PTFs applied to VTCS and HSC B Configuring the LSMs and RTDs The SL8500 is a new Library architecture This is not new news but it is worth repeating because it means changing the way we currently think about VSM configurations There is a smaller capacity per logical LSM less tape drives p
