Re: RHEL 6 cannot access more then 2 TB HP d220sb storage
The "fdisk" command uses & creates DOS-style partition tables, which cannot handle more than 2 TB. This is a design issue: the partition table format was designed in the 1980s, was already extended beyond the original design by LBA, and is now hitting its ultimate design limit.
If you want to use partitions on disks larger than 2 TB, you should be using parted (or gparted, its GUI version) instead. It can create GPT-style partition tables, which don't have such limits. Alternatively, you might completely skip partitions and use LVM instead.
But if the system hangs when you try to access the storage, something is seriously wrong. Is there any error messages in the syslog (the log files are in directory /var/log)?
