for CD-ROM-default mount point is /cdrom/cdrom0, ro for

read only

#mount -F hsfs -o ro <dev name> <mount point>

example:

#mount -F hsfs -o ro /dev/dsk/c0t1d0s0 /cdrom/cdrom0

for DVD-ROM-default mount point is /cdrom/cdrom0, ro for

read only

#mount -F udf -o ro <dev name> <mount point>

example:

#mount -F udf -o ro /dev/dsk/c0t1d0s0 /cdrom/cdrom0

for floppy-device name is /dev/diskette0

#mount -f pcfs <dev name> <mount point>

#mount -F pcfs /dev/diskette0 /dir1

There are 3 types of file system -

A] Disk based file system (pcfs, ufs, udfs, hsfc)

B] Distributed file system (nfs, autofs, cachefs)

C] Pseudo files system (virtual file system, memory based

file system, swapfs, procfs, mntfs, dev, & tmpfs)

# coreadm –e –f <path of core file>

from local zone you can cat /etc/global-zone-name to find

vmstat is tool used to check current memory utilisation

status.

it reports memory statistics of process,virtual memory,

disk,trap,and CPU activity.

Basic synctax is

vmstat <options> interval count

option include

paging -p , cache -c ,.interrupt -i

if no option specified then it will show info. about

process , memory , paging , disk ,interrupts & cpu

interval- is time between 2 successive output. it will
