  • 1.  AIX rootvg + Flashsystem Safeguarded Copy

    Posted 04/07/26 04:39 PM

    Hi everyone,

    I'd like to ask for your input and hear your thoughts if you have any experience testing the following: FlashSystem Safeguarded Copies of AIX rootvg (including VIOS).

    This is working under the premise that we will always be recovering this copy to the same LPAR profile.

    I've taken some of these copies in the past, tested the recovery process, and it worked successfully.

    I would love to hear your thoughts regarding copy integrity, the best methods, prerequisites, best practices, or any other more effective approaches (specifically regarding OS and component integrity, RPO, and RTO).

    Thanks in advance!

    My apologies if this topic has been discussed before. I did a quick search and couldn't find anything related.

    Hi Bruno,
    The Restore from Snapshot feature, introduced in the 9.1.x firmware, is exactly what you need for this use case. 
    There are a few points to consider:
     
    Integrity: Since these are storage-level snapshots taken while the OS is online, it is crash-consistent. Upon recovery, AIX will probably initiate an fsck during the boot process to ensure file system consistency. This is standard and is usually completed successfully.
     
    Tip: If possible, running sync; sync on the AIX side just before the safeguarded copies (via script for example) can help flush the buffer cache to disk, making the recovery process even smoother.
