I am needing to create a new identifier variable for a data set which has no ID variable in the original file. I am basically wanting to take the count of each row and add "sd" in front of it - so it would look like so sd1 sd2 sd3 sd4 sd5 etc....... I have no idea how to do this. I am a SAS user trying to learn R. This question may have been answered previously, but I could be searching for it incorrectly. Thank you for any assistance you can provide.

Hi all, just after sending a message to sunmanagers I realized that my question should rather have gone here. So sunmanagers please excus ethe double post: I have inherited a X4140 (8 SAS slots) and have just setup the system with Solaris 10 09. I first setup the system on a mirrored pool over the first two disks pool: rpool state: ONLINE scrub: none requested config: NAME

...rs for the drive were incrementing in iostat -En output. Nothing was seen in fmdump. Unfortunately, it took about three hours for ZFS (or maybe it was MPT) to decide the drive was actually dead: May 5 07:41:06 dev-zfs4 scsi: [ID 107833 kern.warning] WARNING: /scsi_vhci/disk at g5000c5002cbc76c0 (sd4): May 5 07:41:06 dev-zfs4 drive offline During this three hours the I/O performance on this server was pretty bad and caused issues for us. Once the drive "failed" completely, ZFS pulled in a spare and all was well. My question is -- is there a way to tune the MPT driver or eve...

I have just recently (physically) moved a system with 16 hard drives (for the array) and 1 OS drive; and in doing so, I needed to pull out the 16 drives so that it would be light enough for me to lift. When I plugged the drives back in, initially, it went into a panic-reboot loop. After doing some digging, I deleted the file /etc/zfs/zpool.cache. When I try to import the pool using the zpool

Hi, I have installed b_78 on a Dell 2950 and booting to bare metal works fine but when I try to boot using the grub entry Solaris xVM it will boot to the point where it displays the uname info and then just stays there. It will not boot past that point. I have enabled VT technology in the BIOS (but only after the installation). Where/what can I look at to trouble shoot this? I am new to xen and

Hi All, I''ve just built an 8 disk zfs storage box, and I''m in the testing phase before I put it into production. I''ve run into some unusual results, and I was hoping the community could offer some suggestions. I''ve bascially made the switch to Solaris on the promises of ZFS alone (yes I''m that excited about it!), so naturally I''m looking

G''day, all, So, I''ve decided to migrate my home server from Linux+swRAID+LVM to Solaris+ZFS, because it seems to hold much better promise for data integrity, which is my primary concern. However, naturally, I decided to do some benchmarks in the process, and I don''t understand why the results are what they are. I though I had a reasonable understanding of ZFS, but now

Hi, I just had my Dell R610 reboot with a kernel panic when I threw a couple of zfs clone commands in the terminal at it. Now, after the system had rebooted zfs will not import my pool anylonger and instead the kernel will panic again. I have had the same symptom on my other host, for which this one is basically the backup, so this one is my last line if defense. I tried to run zdb -e
