Question & Answer
Does IBM Spectrum Protect support 4k Advanced Format disks for the server DB?
This is not supported at this time. The reason for this is that DB2 does not support it. The DB2 11.1 documentation for CREATE TABLESPACE still documents this restriction:
NO FILE SYSTEM CACHING
Specifies that all I/O operations are to bypass the file system-level cache. LOB and Long
field data in SMS tablespaces are excepted.
Note: You must format the disk device to have a disk sector size according to the following
Operating system Disk sector size
AIX 512 bytes
Solaris 512 bytes
HP-UX 1024 bytes
Linux 512 bytes
Windows 512 bytes
So based on this, this is a limitation for IBM Spectrum Protect as well at this time.
