Figure 4-17. Volume Size Screen 7. In the Volume Size screen, use the Capacity field and drop-down list to select the size to be allocated for this volume. Do not exceed the maximum volume size shown in the screen. Click Next. The resulting volume capacity may be slightly different than the nominal size specified, depending on the type of volume, the chunk size, and the number of drives used. By default, a block size of 512 bytes is assumed for all SCSI communication between your host server and all volumes. However, if you wish to access a volume that is larger than 2TB from a host operating system that only supports 32-bit addressing (such as Windows XP), you must change the block size setting for that volume from 512 bytes to 4096 bytes using the Advanced Volume Setting tab (see section 4.4.5) before you establish an iSCSI session and connection to that volume. Once a new block size has been selected and used for a connection to a volume, the block size must not be changed. You can also change the system-wide default block size for all new volumes by using the Advanced Settings tab in the System Administration view (see section 6.2.13). However, changing the system-wide default block size will have no effect on any existing volumes. The Grant Access screen appears (see Figure 4-18). 48 Chapter 4 Managing Volumes
