Element	Purpose	Key Considerations
-D	Indicates that you want to take the chunk down	None.
-o offset	Indicates, in kilobytes, the offset into the disk partition or unbuffered device to reach the chunk	Restrictions: Unsigned integer. The starting offset must be equal to or greater than 0. The starting offset plus the chunk size cannot exceed the maximum chunk size. The offset must be a multiple of the page size. The maximum offset is 4 terabytes. References: For more information, see allocating raw disk space on UNIX, in the chapter on managing disk space in the IBM Informix Administrator's Guide.
-O	Indicates that you want to restore the chunk and bring it online	None.
-p pathname	Indicates the disk partition or unbuffered device of the chunk	Additional Information: The chunk can be an unbuffered device or a buffered file. When you specify a pathname, you can use either a full pathname or a relative pathname. However, if you use a relative pathname, it must be relative to the directory that was the current directory when you initialized the database server. References: For pathname syntax, see your operating-system documentation.
-s	Indicates that you want to change the status of a chunk	Restrictions: You can only change the status of a chunk in a mirrored pair. References: For more information, see changing the mirror status in the IBM Informix Administrator's Guide.
-y	Causes the database server to respond yes to all prompts automatically	None.
blobspace	Names the blobspace whose status you want to change	References: Syntax must conform to the Identifier segment; see the IBM Informix Guide to SQL: Syntax. For more information, see changing the mirror status in the IBM Informix Administrator's Guide.
dbspace	Names the dbspace whose status you want to change	References: Syntax must conform to the Identifier segment; see the IBM Informix Guide to SQL: Syntax. For more information, see changing the mirror status in the IBM Informix Administrator's Guide.
sbspace	Names the sbspace whose status you want to change	References: Syntax must conform to the Identifier segment; see the IBM Informix Guide to SQL: Syntax. For background information, see changing the mirror status in the IBM Informix Administrator's Guide.
