New disk presentation allows sdb but not sda to be partitioned
 
Hi we have un-presented a SAN disk and re-presented the same LUN to a new install of Oracle Unbreakable as we wish to get a RAC cluster working. The local disk is a HP Smart Array, and platform a HP blade 480
The /dev/sda cannot be fdisked , although we can see it on the proc/partitions list
104 0 71652960 cciss/c0d0
104 1 104391 cciss/c0d0p1
104 2 71545477 cciss/c0d0p2
104 16 71652960 cciss/c0d1
104 17 71649868 cciss/c0d1p1
253 0 141131776 dm-0
253 1 2031616 dm-1
8 0 209715200 sda
8 16 209715200 sdb
8 17 1959898 sdb1
8 18 9775552 sdb2
8 19 97667167 sdb3

[root@tstesx12 usr]# fdisk /dev/sda
Unable to read /dev/sda

a dmesg|tail shows...
Buffer I/O error on device sda, logical block 0
sd 1:0:0:1: Device not ready: <6>: Current: sense key: Not Ready
Add. Sense: Logical unit not ready, initializing command required

end_request: I/O error, dev sda, sector 8

Would this be a SAN preseation issue or as we can use /dev/sdb then ignore the anomaly?
