  8. 8. 8 © 2013 IBM Corporation IBM Power Systems MKSYSB Support of Live System Backups • Motivation – Desire to reduce system downtime (inactivity) when using the native system backup tools for AIX. – Additional requirement for guaranteed image integrity (upon completion of an image capture). • Details – Provides a consistent backup even in the presence of a workload that is creating and deleting temporary files. – Create a volume group backup (mksysb, savevg, savewpar, mkcd, or mkdvd) using the new -T flag while such a workload is running. There should be no errors about missing files, even if files were deleted while the backup was running. – Requires either pre-GA AIX 6.1 TL9 or pre-GA AIX 7.1 TL3 • Benefits – Includes the ability to capture a system backup without the worry of having files change prior to completing the archive. – Ideal for capturing backups of production systems.. where quiescing the machine isn't always possible. meta-data SW OS mksysb
  9. 9. 9 © 2013 IBM Corporation IBM Power Systems AIX WPAR Lifecycle Management Alt-Disk-Copy for WPARs • Motivation – Desire to exploit advantages of alt_disk_copy for an LPAR that includes WPARs. In particular, desire to “roll-back” to original LPAR and original WPARs. – Desire to create an alternate copy of a WPAR, make experimental changes to the WPAR, and quickly roll-back to the original WPAR if needed. • Details: – New chwpar command options • Create alternate copy of the WPAR “bootset” • Start the WPAR from a different “bootset” – Does not apply to Versioned WPARs (5.2 or 5.3) – Requires pre-GA AIX 7.1 TL3 • Benefits – Same maintenance methodology possible for LPARs with WPARs – Quick roll-back capability for WPARs Workload Partition Application Server Workload Partition Web Server Workload Partition Billing Workload Partition Test Workload Partition BI NetworksDisk or NFS storage AIX global Instance Workload Partition Application Server Workload Partition Web Server Workload Partition Billing Workload Partition Test Workload Partition BI NetworksDisk or NFS storage AIX global Instance
