Hi all,
We have this NX3100 + PV MD1200 configured as NFS server running Debian. OS is installed on 2x 2.5" 136GB SAS internal disks configured in RAID1. One of the OS disk is having media errors and we would like to exchange this disk before it fails.
Enclosure Device ID: 32
Slot Number: 13
Drive's position: DiskGroup: 0, Span: 0, Arm: 1
Enclosure position: N/A
Device Id: 13
WWN:
Sequence Number: 2
Media Error Count: 9
Other Error Count: 1
Predictive Failure Count: 0
Last Predictive Failure Event Seq Number: 0
PD Type: SAS
System is out of warranty/support. I ordered new SAS disk from dell and I got 300GB SAS. Since it is internal disk, following the manual system needs to be shutdown to exchange the disk. I found youtube video "Dell PowerEdge R510 Internal Hard Drive Replacement". In this video its mentioned to be very careful when exchanging internal disk because system is off and on boot raid controller can mirror new empty disk to old OS disk destroying the OS. Usually when I exchange hot swap disk I put it in offline mode and prepare to remove with megasascli.
I plan to make full OS disk image before exchange. I will also do the same thing like with hotswap disks, putting failing disk in to offline mode, prepared to remove.
Did someon have same problem? How did you do the exchange?
Best,
Drazen
