Hello!
I recently inherited system administration duties for a SUN v880 box. The system has 6 physical hard disks.. In doing some basic maintenance, I found they're configured for mirroring. I ran the metastat and metadb commands, and many of the mirrors are showing they are in need of... (5 Replies)

Hi all,
I guess most of you have seen this error message while installing Solaris 10 on an x86 platform. I got the error message while installing from DVD ISO on my home VMWare ESXi server.
It took me a long time to figure the exact issue and a subsequent solution. the solution is very... (1 Reply)

cmdk
cmdk(7D) Devices cmdk(7D)NAME
cmdk - common disk driver
SYNOPSIS
cmdk@target, lun : [ partition | slice ]
DESCRIPTION
The cmdk device driver is a common interface to various disk devices. The driver supports magnetic fixed disks and magnetic removable
disks.
The block-files access the disk using the system's normal buffering mechanism and 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 sin-
gle read or write call usually results in one I/O operation; raw I/O is therefore considerably more efficient when many bytes are transmit-
ted. The names of the block files are found in /dev/dsk; the names of the raw files are found in /dev/rdsk.
I/O requests to the magnetic disk must have an offset and transfer length that is a multiple of 512 bytes or the driver returns an EINVAL
error.
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 fdisk partition for Solaris software. Other slices may be used for usr file systems or system reserved area.
Fdisk partition 0 is to access the entire disk and is generally used by the fdisk(1M) program.
