Невозможность создать VMFS Datastore

Бывает, при переключении уже использовавшихся где-то LUN'ов на дисковом массиве к ESX'ам возникает ошибка: "Unable to read partition information from this disk"

[root@esx2 root]# esxcfg-vmhbadevs
vmhba0:0:0 /dev/cciss/c0d0
vmhba1:0:1 /dev/sda
vmhba2:2:13 /dev/sdt

[root@esx2 root]# fdisk /dev/sdt

Command (m for help): o
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.

The number of cylinders for this disk is set to 36643.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

Command (m for help): w
The partition table has been altered!

Calling ioctl() to re-read partition table.
Syncing disks.

Теперь можно создавать VMFS Datastore.
