upgrading disk on DL360

[Daniele Palumbo]

hello to all, i am a new user in this forum.

i have a DL360 (g1) in production.
i am going to change my 18 GB to 72.8 GB.
and if i do not have to reboot, well that's good!

the question is:
how can i proceed?

my thoughts:
1) extract one 18 GB disk, insert one 72.8 GB.
2) wait for happy end
3) extract second 18 GB, and insert the other 72.8 GB.
4) relax, take a week of relax, see how disks are doing the job :)
5) resize the array. or, if i can't, create a new array with free parts of disks.

again: how?

i have found hpacucli, but i have to use version < 7.60, cause i have "Integrated Smart Array Controller".

now on, this is my actual configuration:
---
=> controller slot=0 physicaldrive all show


Integrated Smart Array in Slot 0

array A
physicaldrive 2:0 (port 2:id 0 , Parallel SCSI, 0 Byte, Failed)
physicaldrive 2:1 (port 2:id 1 , Parallel SCSI, 0 Byte, Failed)

=> controller slot=0 logicaldrive all show


Integrated Smart Array in Slot 0

array A
logicaldrive 1 (16.9 GB, RAID 1+0, OK)

=>
---

i have found, in help, something that may help:
---
[size=#|max|?] [forced]
Extends the logical drive to the specified size. The implied units are MB.
max will extend the logicaldrive to its maximum size.
can be any valid logical drive target
---
but speaks about logical drive.

is this what i need?
what i have to do to let linux know about new partition size?

thanks!
d.

Shalom,

I've tried the very same thing on an DL360.

If you are running RAID 1 your plan can work.

I would suggest pulling out the primary disk first. You can then immediately put in a clean (it must be a clean disk) larger primary.

Then be sure the sync is done (PSP provides a status that can be accessed via a http browser). Then repeat.

Where you may get into trouble is actually utilizing the new space. That depends on your distribution. Reveal that information and further advice can be given.

Hi, thanks for the reply.

first of all, a question: what PSP stand for?

then,
I am using gentoo, but how kernel module can be related to show up or doesn't show up new logical space?

i have already installed the hpsmh, and also cpqacuex, started all but cpqacuex is not found by hpsmh.
dunno why, then i found hpacucli, and i hope this was all that i need!

is sufficent hpaculi

to know if the resync is done?

thanks

I did the upgrade yesterday.

unfortunatly with HP CLI 7.50.18.0, and Firmware Revision: 1.42 on smart array, all the modify command are not available.

but, i accomplished anyway with following procedure, without using any cli or things like that, i report that but:
KEEP IN MIND, I AM NO RESPONSABLE IF YOU LOSE YOUR DATA
and, please try to make a backup.

my setup have raid1 with two identical disk.
i replaced that disks with two identical, but bigger, disk.

that is:
- replaced disk 1 with a BLANK disk (if needed, dd if=/dev/zero of=addressofsingledisk)
- waited the resync, you can view it because the middle led is blinking while resync. or you can use arrayprobe (http://www.strocamp.net/opensource/arrayprobe.php)
- replaced second disk, with a BLANK disk, and waited for resync.

now the crazy part:
- reboot, and go in the array configuration of bios (for me, F10)
- delete array, it will show a warning about data loss. delete it.
- recreate array, of course in raid1.

this is done.
now you have an array of the right size, and you can use free space simply by partitioning it.

of course, you can use partition magic or parted or simply fdisk/cfdisk/...

bye
