透過 Veritas Operations Manager 集中管理
統一實體與虛擬環境的儲存管理工作
移轉到 Storage Foundation
•當工作負載變大時會提高效能及穩定度
• Volume Manager
– vxvmconvert
• Converts LVM volumes to VxVM
• File System
– vxfsconvert
• Converts Ext2/3 to VxFS
• Be aware that file system journal will be located at end of file system
– Fix with Multi-Volume File System

x. 執行 fscdsconv指令 (改變 Byte Order)
[root@rhel4u6 /]# /opt/VRTS/bin/fscdsconv -e -f /tmp/1.out -t os_name=SunOS,arch=x86 /dev/vx/dsk/oracle_dg/oradata_lv0
UX:vxfs fscdsconv: INFO: V-3-26040: Please verify if the following details identify the migration target for /dev/vx/dsk/oracle_dg/oradata_lv0:
Operating system : SunOS
Operating system version : any
Architecture : SPARC
VxFS version : any
Bits : any
UX:vxfs fscdsconv: INFO: V-3-26037: Would you like to proceed further with migration? (ynq) y
UX:vxfs fscdsconv: INFO: V-3-26042: The filesystem does not need to be byteswapped for use on this target.
UX:vxfs fscdsconv: INFO: V-3-26130: There are no files violating the CDS limits for this target.
UX:vxfs fscdsconv: INFO: V-3-26034: Since no byteswapping was required, the file /tmp/1.out has not been used.
UX:vxfs fscdsconv: INFO: V-3-26045: The filesystem is now ready for use on the specified target.
如果沒有必要執行轉換動作的話, 這個步驟可以省略 (所有格式都是 little endian 狀態).
如果是在 AIX, HP-UX, 及 Solaris 系統之間執行 PDC, 則不需要執行此指令
如果是在 AIX/HP-UX/Solaris 與 Linux 系統之間執行 PDC, 則需要執行此指令
