# share -F nfs -o rw=[accesslist] /path/to/share

# share -F nfs -o rw=client1,client2 /export

# share -F nfs -o rw=@client1:/export /export

# showmount -e 

On NFS client

# mount -F nfs -o [options] [NFS_server]:[mountpoint]

  # mount -F nfs  10.11.1.xxx:/BARMAN /BARMAN

  # mount -F nfs -o rsize=32768,wsize=32768  10.11.1.xxx:/BARMAN /BARMAN

To create a RAID volume, type:

# raidconfig create raid options -d disks

For example, to create a RAID 0 volume with a stripe size of 128 Kb and read-ahead caching enabled on controller 1, type the following command:

# raidconfig create raid --stripe-size=128 --read-cache=enabled -d c1d0,c1d1

    To delete a RAID volume, type:

# raidconfig delete raid option

For example:

• To delete RAID volume 1 created on controller 1, type:
  # raidconfig delete raid -r c1r1
• To delete all RAID volumes, type:
  # raidconfig delete raid --all

Scaning FC_LUN's in RedHat linux

# fdisk -l 2> /dev/null | egrep '^Disk' | egrep -v 'dm-' |wc -l

# ls /sys/class/fc_host/
host1  host8

For FC
#  echo "1" > /sys/class/fc_host/host1/issue_lip
#  echo "1" > /sys/class/fc_host/host8/issue_lip

For SCSI

#  echo "1" > /sys/class/scsi_host/host1/scan
#  echo "1" > /sys/class/scsi_host/host8/scan


# fdisk -l 2> /dev/null | egrep '^Disk' | egrep -v 'dm-' |wc -l
