7400 Disk Array

armdsp -a va7400   <-- real time display of the disk array
armmgr -D va7400 HPA6189A00SG218H0024
armdiscover  /opt/sanmgr/commandview/client/sbin    -->  Tells us the serial number

ioscan -fnc disk | more

cvui - creates luns

• Choose storage array
• Create LUN
• Find last LUN
• Create with new lun number
• View existing luns

Process to export disk configuration to a file:

• sam --> actions-->export
• volume group name  --> mapfile name

Fibre Channel Devices

ioscan -fknC fc  <-- Lists fibre channel adapters.

To identify the devices:

ls -l /dev/fc*

fcmsutil - utility for fibre channel operations
fcmsutil /dev/

Procedure to run fcmsutil on a fibre channel:
ioscan -fnC disk|more   --> Identify hw path of fibre channel adapter
ioscan -fnH 1/0/0/0  -->  Identify device of fibre channel adapter

or ls /dev/fc* on older adapters (arbitrated loop)

fcmsutil /dev/fcms2 stat  -->  fcmsutil that shows status of fibre channel adapter

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

Bootup/Shutdown

shutdown -r 0 --> reboot
shutdown -h now  --> shutdown and halt
shutdown 0 --> shutdown to single user mode
reboot 0 --> reboot
init 1 - single user mode
hpux -is  boots single user mode

Interupting the boot process:

• Configuration Menu
• Information Menu
• Service Menu

GSP Mode

• From the console hit
• Hit at the GSP console login (default is no password)
• Now low level commands can be entered
• ps  --> power status

To reboot to single user mode:

1. shutdown -r 0
2. hit during 10 sec window to interrupt reboot
3. enter:
4. interact with ipl? yes
5. hpux -is  (i=init, s=single user)

To reboot manually to init 3 level

1. shutdown -r 0
2. during 10 sec window
3. bo
4. interact with ipl  --> yes
5. hpux -is   (i=init, s=single user mode)
6. mount -a
7. init 3

Startup/Shutdown Scripts

/sbin/init.d
/sbin/rc0.d                                These are all linked to actual scripts in /sbin/init.d
/sbin/rc1.d
/sbin/rc2.d                                scripts with k are kill scripts and scripts with s are start scritps.
/sbin/rc3.d
/sbin/rc4.d

/etc/rc.config.d    --> Scripts

C:\Documents and Settings\$Username$\Application Data\Microsoft\Outlook folder

Once resolved, the email should like the one shown below:

Searching for Large Items (exchange)

Best Practice Definition

Retaining unnecessary messages, especially those that contain large attachments,  quickly takes up the storage space on the Exchange server. This can lead to a crash of the server, leading to down time for users. Thus, it is important to apply correct storage practices to these messages. (Exchange is not meant for long term storage of information!)

Best Practice Usage

One of the easiest way to clean up storage space is to go after the largest items first.  Here the steps to find the large items you have in your mailbox:

·         Along the left hand side, near the top, click on the item that starts with “Mailbox”.

·         Go to Tools, Find.

·         Click on the Advanced button.

·         In the upper left hand corner, type “200” in the box next to “At Least” item.

·         Click on OK

·         Click on Find Now.

Once these search results are completed, you can sort the items by Size (click on the Size bar) and concentrate on removing the larger items first.   Please follow the best practices for saving 

Retaining Individual E-mail Messages

Best Practice Definition

Retaining unnecessary messages quickly takes up the storage space on the Exchange server. This can lead to a crash of the server, leading to down time for users. Thus, it is important to apply correct storage practices to these messages. (Exchange is not meant for long term storage of information!)

Best Practice Usage

When you receive a message that you need to save beyond 365 days, you should save the message in your "My Documents" directory on your hard drive (which is backed up to your O: drive daily).  After saving the attachment, delete it from the message or delete the entire message itself.

Steps to save a message:

·         Highlight or Open the attachment and choose "File", "Save As".

·         Select the appropriate directory in My Documents (preferred storage location).

·         Select the File Type RTF format for text only                                                                                                      MSG format to save as message format with attachment 

·         Click OK.

·         Delete the original Message.

Steps to save multiple messages

                       

·         Open explorer session and create folder for messages to be saved in

·         Open outlook

·         Go to the outlook folder (eg Inbox)and select multiple messages to move. You can select non-adjacent messages by holding down the CTRL-key                                        

·         Ensure all messages to move are highlighted.

·         Click and drag to start tool bar – ensure cursor is over explorer session

·         Explorer session will maximise

·         Drop messages into required directory.

·         Check that messages have copied across OK

·         Delete messages from outlook

NOTE:

If your message has the same subject line as an existing one in the destination folder, it WILL OVERWRITE the original message.

When copying multiple messages – all  messages should be highlighted at message level not folder name. Complete folders cannot be copied across by the folder name -  this will create shortcuts to the original message.

Always check that the messages have successfully copied across (and ensure that they are not shortcuts) before deleting them from outlook.

Ensuring that the Deleted Items Folder is set to “Empty on Exit”

Best Practice Definition

Until the final implementation of the “Automatically Delete messages in the Deleted Items folder after 2 days” process is implemented, this is a good area to look for wasted storage.

Best Practice Usage

·         Go to Tools, Options.

·         Select the General Tab.

·         Make sure that the check box labeled “Empty Deleted Items folder upon exiting” is checked.
