CIFS (Samba)

/opt/etc/samba/smb.conf

Device Management

HP-UX is a hardware path based operating system.  When it boots up it does a hardware detection.  It then compares the hardware that it detects with the hardware that is listed in /etc/ioconfig.  If new hardware is detected, it is assigned the next available configuration information in the proper hardware path.

rmsf - remove special files
insf - install special files

insf -C disk -e   <-- This command will re-install all of the device files for the class "disk"

lsdev   <-- Lists devices and drivers in the system

ioscan   <-- searches for all devices and displays their hardware path
ioscan -fnC disk  <-- searches for all devices of  class (C) disk
ioscan -fnH  <-- searches for a LUN

last 2 digits of hardware path in the LUN in octal  (1/12/0/0.1.23)

Disk Devices

A disk device will have a name in the following format:  c#t#d#

c# is the card number
t# is the target number
d# is the LUN - this is normally 0 unless RAID is being utilized


scsictl -a /dev/rdsk/c?t?d?  <-- display control parameter information about the disk device
scsictl -a -m queue_depth=4 -m queue_depth /dev/rdsk/c?t?d?      <-- sets the queue depth

CD-ROM Devices

nohup /usr/sbin/pfs_mountd &  - starts process
nohup /usr/sbin/pfds &  - starts process

pfs_mount -o xlat=unix /dev/dsk/c0t1d0 /cdrom        - mounts cdrom

Cdrom won't eject:

1. pfs_umount -c OR
2. kill -9 pfs_mountd and kill -9 mountd

Cdrom won't mount using:  pfs_mount -o xlat=unix /dev/dsk/c0t1d0 /cdrom

1. nohup /usr/sbin/pfs_mountd &
2. nohup /usr/sbin/pfsd
3. /usr/sbin/pfs_mount /cdrom    <-- this uses mounting information in /etc/pfs_fstab
