add anew storage device

[mahmoud khalefa]

Dear all ;
nice to meet you.
acorrding for the big database that we need in my work they decide to add anew storage device can you please tell me a detail Steps "please i need all command with it option and full example for that" to do that and how to configure it with the oracle database.
and what is the best way to change the server IP and netmask

[Robert-Jan Goossens]

Hi,

the second part of your question is the easy part.

# /sbin/set_parms ip_address

# /sbin/set_parms addl_netwrk

Changes you make using set_parms will take effect after rebooting the system.

Could give us some more info about your server and the disks you have to add.

new disk? + new filesystem? + new volumegroup? + adding space to old filesystem ?

Kind regards,

Robert-Jan.

For an HP-9000 server, all you need to do is add the disk. If there is an open slot for a hot-swappable disk, it can be added while the machine is running.

Otherwise you'll need to shut down the system, add the disk, restart the system.

Assuming such details as the SCSI address are compatible with your system, when the system comes up, you're ready to go.

Based on your implied level of experience, I'd use sam
Disks to configure the disk.

You mentioned oracle.

Oracle works best with RAID 10. Thats disk to disk mirroring.

In hpux that is accomplished with an add in product called mirror/ux

Once installed mirroring is accomplished with a very simple command.

lvextend -m 1 /name_of_fs /dev/dsk/c#t#d# the # signs being the location where you want the mirror copy to be.

There is nothing to do with IP addresses. Even if you get an external disk array, you don't want your your oracle traffic on you lan in some NAS setup.

Hope this was helpful for you.

dear all;
i still didn't know what kind of storage device but i think that it will be external -SCISI device

Mahmoud:

First, don't forget to assign points to the above.

Second, find out if its JBOD or a RAID storage devices. (* JBOD = Just A Bunch Of Disks *) (* RAID = Raid 0, 1, 5, = Redundant Array of Inexpensive Disks, like EMC or XP. *)

For an external SCSI disk in a JBOD a Jamaica or Ultra or Seagate are popular. Find a space in the disk bay and determine you NEW TARGET address. This last part is critical especially if you've got dip switches preset in the disk enclosure. You should map out all of your SCSI targets to each disk to determine vacancies for NEW TARGETS. For example, disk c1t5d0. The c1 is for controller one, the t5 is for the fifth target on controller one, and the d0 is for luns or partitions and typically only used in disk arrays.

If your disks have numbers in the d parameter like c1t5d5, you've got a disk array.

"...ioscan -fknC disk..." for all disks.

Note: Look for dip switches in the external enclosure. If you have these then repsond because reading the dip switch can be a little tricky.

Hi,
Addition to above responses.
after plug new disk and gor device file.
if you are not familier with LVM.
use sam to create new logical volume by goto disk and file system menu.
after that you will get new lvol mount to a mount point.
verify with bdf , then you are ready to use to to store datafiles.

Dear M. Frederick Steele
thanks alot for your reply and for other reply but for not ussign points till now that because i'm still didnt try that because they still didn't get the storage device which i will add and after changing the IP so a'm preffered to assign points after doing that to give every one the actual point he worth
thanks alot
