RAID Volume expansion in Windows 2000 server
server 1 and server 2
****************************************
2*36.4GB
RAID 1+0 is created.
There are 2 logical drives i.e C: and D:
Customer want to expand D:.Is this possible?If yes how can we go ahead?
server 3
*********************************************
total 5 disks of size 36.4 GB
Two configured as RAID 1+0 with 2 logical drives C: and E:
3 disks configured as RAID 5 with 2 logical drives D: and F:
Customer want to expand C: and D: preferably.
Please suggest me whether this expansion is in place or do we need to break the existing RAID and recreate them?
Waiting for your response.
Thanks in advance.

Re: RAID Volume expansion in Windows 2000 server
We have HP DL 380 G3 model servers.All the disks are configured as basic.
For server 1 and server 2 can I expand the D drive without breaking the existing mirror?If I can expand then the redundacy will be retained?
For server 3
Can I add one 72GB disk and expand the RAID5 volume while retaining the redundancy?
Please suggest as the attached threads were not much clear.
Regards
Sitaram

Re: RAID Volume expansion in Windows 2000 server
did you check previous links I posted
I think you think your scenario is different but in both you want to add more space to a existing RAID levels no matter if it is RAID 0, RAID 1, RAID 5, it is the same procedure
---1.For the server which have RAID 1+0 configured how can i add the disks and expand the drives?----
--2.For the other server which has RAID 1+0 and RAID 5.
I want to add the disks and expand the drives.Please suggext me on both the scenarios. ---
- you add your new HDDs
Expand RAID (wait some time)
Extend RAID
use either diskpart or any other tool to extend the new space within windows
also I attached again the PDF file that explained that (added it the other threads)

Re: RAID Volume expansion in Windows 2000 server
I have gone through the previous attachments what you have provided.But I have a lot of doubts as I have not done this before and when I have asked others in my team I received different perceptions from different people.I will make you more clear on this below so that I should not goof up with the client's important servers.
We will go one by one now.I will start with one server which has got below configuration.
I have Array Configuration Utility 7.0.1.0,Smart Array 5i Controller .
RAID 1+0 configured with 2*36.4gb drives.
The disks are Basic disks.
2 partitions in the logical drive i.e C and D.
I have 3*72.8GB drives.If I add these disks in the server can i add the space into C and D drive without breaking the mirror,without reinstalling the operating system and applications?
Will the data be intact?
I have attached the screenshot also.Please check and clarify me.I am asking you too many questions because this is an important server and we cannot afford long outages.
Waiting for your response.
Thanks & Regards

Re: RAID Volume expansion in Windows 2000 server
I have planned the disk space upgradation as below.Please go through and let me know if that will work.
For 2 server which has got RAID 1+0 and 2 partitions in the logical drive as C and D.
1.We will be adding 2*72.8GB disks in the server
2.Create a new RAID 1+0 array
3.Name the existing D: as something else eg. X:
4.care one partition with newly created RAID 1+0 and assign the drive letter as D:
5.Then move the data from X: to D:
Now we are left with 3*72.8GB disks.We will be using these in server 3 which has got one RAID 1+0 and one RAID 5 array.
RAID 1+0 has got 2 partitions i.e C: and E:
RAID 5 has got 2 partitions i.e D: and F:
1.we are planning to move some unnecessary data from C: to E: as E: have suffiecient space unused.
2.Replace the three 36.4GB disks in RAID 5 array one by one with 72.8GB disks and wait for the rebuild i.e replace one 36.4GB disk in the RAID 5 array with a 72.8GB disk and wait for the rebuild.Once this completes do the same for remaining 2 disks.
I hope this will work and I want to know your views on this.

Re: RAID Volume expansion in Windows 2000 server
1 scenario, yes good idea changing partition letters :-)
2 scenario, yes it will work, replacing one by one yes, but Like I told you update everything and do backups if you have the chance

Re: RAID Volume expansion in Windows 2000 server
I have a windows 2000 server where in I am unable to logon to HP system management homepage with administrator password.I have the password listed in a file but if I try that i get the error as login rejected.Do we have any way of resetting the password?

Re: RAID Volume expansion in Windows 2000 server
I have the same old doubt now regarding the expansion of RAID 5.
In the server where i have a RAID 5 which is created with 3*36.4GB disks,I want to expand the logical partitions D and F in this.
My plan is to replace the current 36.4GB disks one by one with 3*72.8GB disks.
I want to know whether this will expand the RAID 5 and I will be able to increase the pation size or not.
Please clarify on this.
Thanks & Regards

Re: RAID Volume expansion in Windows 2000 server
yes of course you will get more space if not what would be idea the idea in adding bigger HDDs if you don't get more space????
it would be useless and waste of money

Re: RAID Volume expansion in Windows 2000 server
But which one do u prefer?Replacing the disks one by one with higher capacity or backing up data and then create the array with new higher disks.
We have 55GB of data in this RAID 5 volume.How much time it may take to rebuild if I replace the disks one by one.

Re: RAID Volume expansion in Windows 2000 server
"But which one do u prefer?Replacing the disks one by one with higher capacity or backing up data and then create the array with new higher disks"
you know there is another discussion about this
which way is much better
I know people that have try both and both work and both some times don't
so rebuilding a HDD takes about 10-15 min per GB so now it's up to you
one by one or backup and recreate
