Preparing Disks to be Proxied Volumes
Refer to About Proxied Volumes for an overview.
Proxy Mode is used for data migration purposes and supports all kinds of existing operating system formats, such as Windows, Unix, AIX, and so on. When a volume with an existing file system and data is proxied, the existing file systems and data are preserved and can be managed by SANsymphony software.
While SANsymphony software supports standard SCSI disk commands (open, read, write, etc.), it does not process proprietary extended SCSI commands for Proxied Volumes.
Proxy mode is not supported for dual path volumes, as these volumes are visible from more than one source.
The DataCore Disk Manager tool is the interface you will use to configure volumes as Proxied Volumes. The DataCore Disk Manager tool allows you to place the storage server in Proxy Mode in order to configure individual volumes as Proxied Volumes. While all logical volumes (non-proxy volumes) managed by SANsymphony software are automatically assigned a SANsymphony volume label, Proxied Volumes are not automatically tagged with this label. Thus, a storage server running in Proxy Mode can discover these volumes and serve them to an application server without altering the live data on the volumes.
WARNING: It is crucial to enable Proxy Mode on the storage server before attaching the original host volumes to the storage server. If the storage server is not in Proxy Mode, it will discover the original host volumes and write data to the disk, possibly corrupting the file system and/or data. If data is written to the disk, the original partition table would be damaged, rendering the disk unreadable by the host. Thus, when you configure a volume as a Proxied Volume, SANsymphony software sees the disk simply as a sequence of disk blocks and does not try to impose its own format on the device.
