>Description:
I've set up second logical drive on the raid
whether I try to label it or whatever (newfs etc.) it shows the following error:
(da1:mly0:2:1:0): SYNCHRONIZE CACHE. CDB: 35 0 0 0 0 0 0 0 0 0
(da1:mly0:2:1:0): error code 0
first drive still works,
if I try to use second drive anyway - system hangs shortly.
hardware used:
platform: intel isp2150g 
raid: mylex acceleraid 352 (firmware 6.00-02)
disks: any (tried IBM DNES , Seagate Barracuda)
raid configuration: 1st logical drive: raid 1 (2 disks on first channel)
                    2nd  : whatever (tried raid1 and JBOD with disks residing either on LVD card(aic 3860q) or not , on the same or different channels)
write cache: write-thru
write cache on disk drives enabled.
>How-To-Repeat:
configure 2 logical drives and try to use both.
>Fix:
