How-ToImportant Notice
The Ahsay™ Universal Backup System provides console access to the "System Management Console" by connecting a keyboard and a VGA monitor to the physical machine.
To prevent unauthorized access to the AhsayUBS System Management Console, it is advised to change the default AhsayUBS administrator password.
If AhsayUBS is running on a VMware host, the tape backup utility is not supported.
As VMware does not support Tape Drives connected directly to ESXi 5.x or above.
Expansion of existing disk volumes is not supported running on either software or hardware backed RAID. Doing so will destroy the volume and cause permanent data loss.
In case you have accidentally expanded an existing disk volume, you can try the steps discussed in Appendix – How to Repair an AhsayUBS Volume to repair it. However, even though the damaged volume is repaired there may still be significant data loss.
The existing ZPOOL(s) created on AhsayUBS v6 using ZPOOL v13 will not be upgraded to ZPOOL v28, only newly created ZPOOLs will be applied with the ZIL (ZFS Intent Log).
For AhsayUBS v6 environments who wish to migrate to UFS to ZFS storage model, only a manual migration method is available. For more information kindly refer to Storage Model Migration.
