NAME
- smartii- Compaq Smart-2 EISA/PCI and
Smart-2SL PCI Array Controller driver
DESCRIPTION
The smartii driver is a driver for Compaq Smart-2 EISA/PCI and Smart-2SL PCI Array Controllers on Compaq Servers. The driver supports magnetic fixed disks and magnetic removable disks.
The Smart-2 and Smart-2SL controllers can be configured using the Compaq Array configuration utility. Each Smart-2 controller can support a maximum of 14 physical disks and each Smart-2SL controller can support a maximum of 7 disks. Only one bus can be used at any time for the Smart-2SL controller. Each controller can support 32 logical volumes.
The block files access the disk using the system's normal buffering mechanism and they are read and written without regard to physical disk records. There is also a "raw" interface that provides for direct transmission between the disk and the user's read or write buffer. A single read or write call usually results in one I/O operation. Raw I/O is therefore considerably more efficient when many bytes are transmitted. The names of the block files are found in /dev/dsk; the names of the raw files are found in /dev/rdsk.
Slice 0 is normally used for the root file system on a disk; slice 1 as a paging area (for example, swap); and slice 2 for backing up the entire Solaris fdisk partition. Other slices may be used for usr file systems or system reserved areas.
fdisk partition 0 is to access the entire disk and is generally used by the fdisk(1M) program.
