HOT SWAPPABLE DISK

I have a ML350 G4 sever with 4 "hot swappable" hard disk. One is showing "imminent failure" messages and needs to be replaced. Never done this before so need to know how to go about this. Do I just pull the drive out while system on or can I replace with system off then reboot? Also the disk we currently have to replace with is of different space size so how would that figure in to the raid 5 array. Don't really care if we lose the extra space on the the HD but will it work until we get same sized spaced HD replaced???

Re: HOT SWAPPABLE DISK

hi

"Do I just pull the drive out while system on or can I replace with system off then reboot?"

yes just pull the bad one out and replace with the new one while server is ON, no problem.
that is the idea when the HDDs are hot swappable. avoid downtime on servers

"Don't really care if we lose the extra space on the the HD but will it work until we get same sized spaced HD replaced???"

yes it's going to work and like you're saying you're going lose the space but it's Ok for you

regards
I hope this can help you

Re: HOT SWAPPABLE DISK

Thank you for the prompt reply...I will indeed try your suggestions and let you know the outcome. But one more question...if the server cannot boot because of the bad disk is swapping at that point (during booting-can't find the drive) a good idea or do I have to go into the array config to tell it to add the HD so to speak???

Re: HOT SWAPPABLE DISK

hi

regarding your last question
"the server cannot boot because of the bad disk is swapping at that point" is it a supposition? right?

while the server is ON you just have to replace the Bad one the new HDD is going to start the rebuild process which automatically will add that HDD to the RAID 5 you dont have to touch anything like Array Configuration Utility, the controller will be on charge of that

Re: HOT SWAPPABLE DISK

Ok...my new hard drive arrived for the server and when the rebuild option came up we accepted the rebuild BUT the server now will not boot..any ideas on what to do next as we just found out the server is no longer under warranty? At a certain point the server ask do we want to hit F8 for "Multi-Initiator configuration" but cannot decide on what to do at this point. We did not use the F8 option so the system started scanning for the SCSI HD but it keeps failing after 3 scan and says no SCSI BIOS installed. If we look at the controller settings it says the logical drive is healthy and ok but does not find any HD's.... Any ideas.

Re: HOT SWAPPABLE DISK

Haven't been able to BOOT after the array sis the rebuild. HP says to reseat everything but thats going to take a while as its in a rack so was hoping for other ideas to get the system booted up to make sure all the data is still there.

Re: HOT SWAPPABLE DISK

When we boot the system where does the boot process stop..........(message)

1:Did the rebuild process complete ?

2:Boot using smartstart and check the array status using ACU...............

Re: HOT SWAPPABLE DISK

The system started the ASR but never gave an indication of completion. After stating Recovery in Progress the system immediatley starts scanning for SCSI drives and after about 2 minutes it fails and then tries 2 more times to rescan for the scsi. After the 3rd scan it says NO SSCI DRIVES INSTALLED, NO SCSI BIOS INSTALLED and then tries to boot from cd, A:drive or PXE. The message then states error loading OS and to restart system. After system is restarted we were able to get into the config screen to view the array setup and checked the array and the logical drive shows that it is ok and shows us what HDs are loaded but when you esc out of that screen the system contines to try and boot and we get back to the same old NO SCSI issue. Will try loading from Smartstart and see what happens. Thanks for your help.
