What are the disk sanitization limits in Data ONTAP 7.3?
Prior to Data ONTAP version 7.3, there was a limit to sanitize only 5 disks at a time.
The Data ONTAP Storage Management Guide does not explain the new guidelines.
Users are working from an older KB: 'disk sanitize' error message: Pattern Limit Reached
The new guidelines for Data ONTAP 7.3 are:
- Previous to version 7.3, if you were sanitizing disks with a random pattern (
-rparameter), then there was a buffer limit of 5.
Only 5 disks could be sanitized at the same time.
- In Data ONTAP 7.3, this limit was changed to 100.
However, if you do not use the random pattern then you can sanitize as many disks as you want, with a few exceptions:
- Both SES control disks in an ESH cannot be sanitized at the same time.
- The root volume cannot be sanitized.
