New to Solaris (Checking/Adding network and harddisk)
Hi all,
As per the topic goes,
q1) how do i check remotely (over ssh) - how many physical network interfaces I really have ? -- if an interface exists before and it got plug out, it must not be show again.
-- i tried dladm show-link and ifconfig -a, but it seems to show a previously existed interface (that is not around anymore -- but i try this on a VM though...)
q2) is there anyway to check how many network cards physically exists and which interfaces are on the individual cards ?
q3) just curious, what does "plumb" really means ? why do we even need it ?
q4) what are the steps that should be done when i add a harddisk into the system ? how do i detect the harddisk without rebooting the system ?
is the steps below correct
a) devfsadm
b) format
c) mkfs
d) mount ?
q5) lastly, can i say that in SPARC system, each partition in a disk = slice while in X86 platform , each partition in a disk is a partition and slices exists INSIDE the partition
Regards,
Noob

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.
