i have an eva 5000 connected to linux redhat server where there is 2 luns presented to the server the first one is 1TB and the second one is 2TB
i have had a power failure after the power is back the server see only one lun of 1TB
i am thinking to unpresent the second lun and present it again to the server does that present any risk as there is a critical data on that lun?
after representing the lun to the server do i have to format it again to be a system file? or everything will be ok?

Re: representing an existing lun to server
Have you tried to just do a rescan on the linux-machine?
In Command View - what is the status of the vdisk that the server cannot see?
If server still does not see it after a rescan and the status of the vdisk is good in CV. Then maybe a restart of the server would be worth a shot before trying the unpresent/present option. You should not have to reformat/recreate file system, because then data would be gone right?
What about a clone - do you have business copy license? That might be worth a shot as well, make a clone and then present that to the same or another server..

Re: representing an existing lun to server
If the lun is good Linux will recognise it and not reformat.

Re: representing an existing lun to server
Any OS recognizes a disk by the metadata it wrote on the disk.If for some reason this metadata is corrupt then unpresenting & representing the drive won't work. U may need to restore the data from a valid backup (Businass copy or tape or any other means).In case if you have the FS structure backup of the disk then that may be restored and tried.
Good Luck
