Applies to

  • Active IQ Unified Manager 9.14 through 9.18 (AIQUM)
  • Windows Server

Issue

  • During a Windows Active IQ Unified Manager (AIQUM) upgrade, the installer exits with a Not Enough Space / Insufficient disk space error.
  • Local volumes have ample free space, so the failure is not a true capacity shortage.
  • The install log (%LOCALAPPDATA%\Temp\netapp_um_install.log) shows a blank folder path and -1 GB free space, for example:
Insufficient disk space! Setup will exit now. Make sure the folder <blank> has minimum 6 GB of free disk space. Available free disk space is:-1 GB.

Cause

  • The Windows installer checkDiskSpace action reads the MySQL data directory from HKLM\SOFTWARE\NetApp\ThirdParty\mysqlDataDir into MYSQL_DATA_DIR.
  • When that registry value is missing or incorrect, MYSQL_DATA_DIR is blank.
  • Free space is queried against an empty path, so the installer reports Available free disk space is:-1 GB and cancels setup.

Solution

  1. Take a VM-level snapshot or other recoverable backup before changing configuration.
  2. Confirm free space on the AIQUM install volume and the MySQL data volume meets the documented minimum.
  3. Open Registry Editor and locate HKLM\SOFTWARE\NetApp\ThirdParty\mysqlDataDir.
  4. If the value is missing or incorrect, set it to the actual MySQL data directory, for example C:\ProgramData\MySQL\MySQLServerData.
  5. Verify the MYSQL84 (or MYSQL8) Windows service ImagePath points to the correct mysqld.exe and --defaults-file path for my.ini under that data directory.
  6. Example elevated command to inspect the service configuration:
    sc.exe qc MYSQL84
  7. If the service path or my.ini references are wrong, correct them, start the MySQL service, and confirm it stays running.
    Example:
    sc.exe config MYSQL84 binPath= "\"C:\Program Files\MySQL\MySQL Server 8.0\bin\mysqld.exe\" --defaults-file=\"C:\ProgramData\MySQL\MySQLServerData\my.ini\" MYSQL84"
    net start MYSQL84
  8. Re-run the AIQUM upgrade installer.
  9. Confirm the upgrade completes and AIQUM services start normally.

Additional Information

Internal Notes

  • Fingerprint in install log: blank Setting MYSQL_DATA_DIR=, then Available free disk space is:-1 GB.
  • Lab recreate: clearing mysqlDataDir before 9.14 to 9.18 upgrade reproduces the false disk-space failure.
