ADIC 2.2 manual Snfs

SNFS

To obtain the number of sectors where the disks are set, use the cvlabel -1command. If you are using disk devices that do not have the same number of sectors, then several disk types can be specified to handle each common number of sectors.

DISK section - Identifies the disk drive that is labeled and available to StorNext FS. A disk type describes a category of disks with a capacity specified in number of sectors. The following parts comprise a disk definition:

•The required keyword Disk preceded by the open bracket symbol ( [ ) and followed by the closed bracket symbol ( ] ).

•On the next line, the words Status UP

•On the next line, the required keyword Type and the name of the disk type assigned to the disk definition. The name of the disk must match the label name of the drive as displayed by the cvlabel -1command. This is how the label names of the Fibre Channel disks are associated with a StorNext FS.

For example:

[Disk CvfsDisk0]

Status UP # UP/DOWN

Type 9GB_drive # A type defined in a DiskType Section

STRIPEGROUP DEFINITION section - Describes a group of disks that comprise a stripe group. One or more stripe groups describe the entire file system. A stripe group is the smallest entity that can be manipulated by a system administrator using the File System Administration utility (cvadmin).

NOTE	All disks defined in any given stripe group must have the same number of sectors,
	as reported by cvlabel -1.
