Every once in a while we run across a slot that goes bad. This might be your problem. This would require a replacement of the DAE to resolve.  glen
Hi there,  we have an old CX700 running Flare 26 and I have two faulted disks the replacement of which the system consequently rejects. Candidate #1 is a 320GB ATA drive in a DAE2-ATA (EMC p/n 005047825) We have about 10 spare disks of thiese (Model 5A30J0 CLAR320, TLA p/n 005048012) which work perfectly in another DAE2-ATA. I replace the disk and it starts to come up with green and amber LED first and then after secondes, only amber remains.  Candidate #2 is in Enclosure 0_0, disk 7, a 73GB 15k FC disk (Model ST373454 CLAR72, TLA p/n 005048600) in a standard DAE (EMC p/n 100-560-130). I tried about 20 disks which work perfectly in other DAEs - but when inserting the fresh disk, it comes up green and amber, amber goes off, green is flashing, amber comes up and green goes off again.  I rebooted the SPs but nothing seems to cure this.  Candidate #1 is bound to a normal user LUN in a RAID5 Raid group Candidate # is bound to a private RAID5 LUN, Write Intent Log).  Is there anything I missed or can try?  Thanks! -Chris
