Hi, I hope this is the correct list to ask this: I have a brand new Compaq Proliant box here, which has a Smart Array 5302 controller (ciss driver). I did some performance testing on it (with bonnie++), but I wasn't quite satisfied, the throughput on the Smart Array is rather low. So I thought I have a look with camcontrol on it: [root@raidtest /home/le]# camcontrol negotiate da1 -T enable Current Parameters: (pass1:ciss1:0:0:0): disconnection is enabled camcontrol: XPT_SET_TRANS_SETTINGS CCB failed, status 0x6 [root@raidtest /home/le]# camcontrol negotiate da1 -v Current Parameters: (pass1:ciss1:0:0:0): disconnection is enabled ciss1: SIM/HBA version: 1 ciss1: supports tag queue messages ciss1: HBA engine count: 0 ciss1: maximum target: 15 ciss1: maximum LUN: 0 ciss1: highest path ID in subsystem: 0 ciss1: initiator ID: 15 ciss1: SIM vendor: FreeBSD ciss1: HBA vendor: msmith@freebsd.ociss ciss1: bus ID: 0 ciss1: base transfer speed: 135.168MB/sec I guess this means that the device is able to do tagged queueing, but the feature is currently turned off. So I tried to enable it and I get this error message: [root@raidtest /home/le]# camcontrol negotiate da1 -T enable Current Parameters: (pass1:ciss1:0:0:0): disconnection is enabled camcontrol: XPT_SET_TRANS_SETTINGS CCB failed, status 0x6 Can anyone tell me what this means? Is the driver lying to me about tagged queueing? Apart from that: the ciss driver is fairly new AFAIK, I didn't find a lot of references to it on the web. Would you recommend it for production use? Is there any testing going for userland tools (status control a.s.o.)? best regards, le --=20 Lukas Ertl eMail: l.ertl@univie.ac.at UNIX-Systemadministrator Tel.: (+43 1) 4277-14073 Zentraler Informatikdienst (ZID) Fax.: (+43 1) 4277-9140 der Universit=E4t Wien http://mailbox.univie.ac.at/~le/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
