CX4-240 Configuration Backup
Hi,
I am a newbie on storage systems so please be patient with my questions if they sound too easy
We have a CX4-240 system and we lost one hard drive (one from those that keep the configuration stored on them).
Question 1: Is the configuration in any kind of "danger" if i just replace the HDD (anything i need to know before i replace it etc)
Question 2: What is the way/ways to backup the configuration of the specific storage?
Thanks in advance for your time,
Charis

Firstly, welcome to the forums, and above all, thank you for being an EMC customer.
Please consider moving this question as-is (no need to recreate) to the proper forum for maximum visibility. Questions written to the users' own "Discussions" space don't get the same amount of attention and can go unanswered for a long time.
You can do so by selecting "Move" under ACTIONS along the upper-right. Then search for and select: "CLARiiON Support Forum"

Answers in-line
We have a CX4-240 system and we lost one hard drive (one from those that keep the configuration stored on them).
I'm assuming that you mean one of the first 5 disks - the OS drives or also called the Vault drives. These disks are mirrored (0 to 2 and 1 to 3) and the config is triple mirrored. So if one of the OS drives fail, there is a backup.
Question 1: Is the configuration in any kind of "danger" if i just replace the HDD (anything i need to know before i replace it etc)
See above.
Question 2: What is the way/ways to backup the configuration of the specific storage?
If you want to back up the user configuration - all the LUNs and raid groups, there is a CLI command "arrayconfig -capture" - see you Command Line Interface manual for a more detailed description of the command and its uses.
