I have a media server where the disks belonging to a specific enclosure are misbehaving. Their response times are extremely high using vxdmpadm iostat and i can also see from the OS logs that they are faulty.
How can i just disable writes to those disks.
I dont want to to completely disable the enclosure as we have data on it that may be used for restore purposes so we need to keep read access to it.
Solved! Go to Solution.
Best you backup the data using a decent backup solution. Keeping information on some faulting disk is not a restoration solution. The day that you'll need the data would probably be the day that those disk finally fail completely.
hi, Great idea, Mariane.
unfortunately we mix different arrays within the same filesystem.
vxdmpadm listenclosure all
ENCLR_NAME ENCLR_TYPE ENCLR_SNO STATUS ARRAY_TYPE LUN_COUNT FIRMWARE
ds5100_ds5300-0 DS5100_DS5300- 600A0B8000479814000000004C5C1B60 CONNECTED A/PF-LSI 10 0730

the one i wanted to disabled for writes was the DS5K. the others are fine.
