The HBA I use is an LSI MegaRAID 1038E-R but I guess it doesn't really matter as most OEM manufacturers such as Dell, Intel, HP, IBM use the LSI 1068e/1078e or the newer 2008e/2018e Megaraid chips which I believe use pretty much the same firmware. So I guess I could change these settings in the

I didn't hot swap the drive but yes, the new drive is in the same "slot" as the old one was (i.e. using the same connector/channel on the fan out cable). What I did was that I turned off the system, and booted it up after disconnecting the physical drive that I suspected was c0t3d0. My guess was

There's nothing odd about the physical mounting of the hard drives. All drives are firmly attached and secured in their casings, no loose connections etc. There is some dust but not more than the hardware should be able to handle. I replaced the hard drive with another one of the same size, I fi

I have now upgraded to OpenIndiana b148 which should fix those bugs that you mentioned. I lost the picture on the monitor but by ssh:ing from another computer the system seems to be running fine. The problems have become worse now and I get a freeze every time I try to access the 8-disk raidz2

I am using a zpool for swap that is located in the rpool (i.e. not in the storage pool). The system disk contains four primary partitions where the first contains the system volume (c7d0s0) two are windows partitions (c7d0p2 and c7d0p3) and the fourth (c7d0p4) is a zfs pool dedicated for Virtual

I have now run some hardware tests as suggested by Cindy.'iostat -En' indicates no errors, i.e. after carefully checking the output from this command, all errors are followed by zeroes. The only messages found in /var/adm/messages are the following: opensolaris scsi: [ID 365881 kern.info] /p.

I also have this problem on my system which consists of an AMD Phenom 2 X4 with system pools on various hard drives connected to the SB750 controller and a larger raidz2 storage pool connected to an LSI 1068e controller (using IT mode). The storage pool is also used to share files using CIFS. Th

The motherboard is AMD based and it has two controllers; one OnChip controller that is integrated into the SouthBridge chip (SB750) and an OnBoard controller using the JMicron JMB362 chip and a JMB322 port multiplier. Both controllers supports both AHCI and Native IDE mode which can be configure

I know about those SoHo boxes and the whatnot, they keep spinning up and down all the time and the worst thing is that you cannot disable this sleep/powersave feature on most of these devices. I believe I have seen a "sleep mode" support when I skimmed through the feature lists of the LSI contro

I've been informed that newer versions of ZFS supports the usage of hot spares which is denoted for drives that are not in use but available for resynchronization/resilvering should one of the original drives fail in the assigned storage pool. I'm a little sceptical about this because even the
