If the drives are unmounted there are several things you can do. You can use a command like fdisk -l or sfdisk -l to list the partitions. Just the partition type may give you some useful information if the partitions where setup correct.y # sfdisk -l Disk /dev/sda: 4177 cylinders, 255 heads, 63 sectors/track Units = cylinders of 8225280 bytes, blocks of ...

Get "cheap" 2.5" SATA drives, they work in SAS enclosures. If you're using a Pxxx series controller (the norm in HP servers) it might not work with just any drives, and is guaranteed to not run at optimum (HP uses custom firmware on their drives to get the most out of them). I really could not recommend one particular drive over another, though I've had good ...

All cables can go bad over time. The conditions that set this up are generally set at manufacture, with some healthy input from operating environment. Yes, they can be damaged by being yanked out. The connectors can get messed up, wires can come unseated, the plastic guides can break. As for just going bad over time, if there was a bad wire join inside the ...

Yes they can. Both by physical handling as without it. Moisture, thermal expansion stress, vibrations, dust etc. It could even be mechanical tolerances: a connector can work fine in one slot and not in another. The annoying thing it may not show up immediately or in a reproducible fasion. I've had a drive cage fail randomly after hours/days of heavy ...

I'd recommend you store the drive offsite in a Turtle Case or Pelican Case: Turtle Cases Pelican Cases They might seem expensive but they are designed and built for this purpose e.g. they have fittings for padlocks/tamper evident seals that you might want to use for the offsite store. I once saw some tapes which were damaged by a leaking toilet above ...

http://technet.microsoft.com/en-us/sysinternals/bb897438.aspx Use this prog to flush the write cache and then it should be safe to remove it. (assuming that your sata controller and drivers support hotswap)

Another useful command along the lines of vol_id as mentioned by Zoredache is blkid - it returns similar information but can also scan all devices in the system, rather than requiring a device to be passed in.

Internal SATA connections are required to work with cables up to 3.3 Feet, yes. eSATA are required to work up to 6.6 (but simply adding a bracket doesn't change what the original port is capable of). That said it's been my experience that most ports are simply built for the higher spec as the costs are negligible and the chips are more flexible that way. I ...

You don't find it because it makes no sense to produce it. This is professional hardware and no one uses SATA anymore. SAS is the game - especially because you can plug any SATA card into a SAS controller. They are downard compatible. Adaptec for example makes only a "unified sata/sas controller". As such, go to LSI and look for a SAS HBA (Host Bus ...

You need a one or two of HP Part Number 487936-B21, it's a 'HP ML350/ML/DL370G6 2 Large Form Factor Drive Kit' and your server can take two of them for up to 8 LFF disks. It'll be easy to replace the drive cages if you've got a screwdriver and some time. Oh and you might want some HP P/N: 389015-001 LFF blanking plates if you want it to look pretty too.

We just did it. You need just 2 parts at a cost of around 100 EUR/USD: the backplane (511787-001) and the cage (511784-001). Additional cables were not needed. Some sites say that the SFF cage can be converted to LFF by removing a metallic inset, but this is not true. The SFF cage included with the server cannot be altered. Maybe in the past the conversion ...

I'll try to answer as best I can, but some of the things you ask are more about personal preference and the features of your software than hard technical facts. Cheap drives are... um... cheap. There are only a few situations where cheap drives are "better" than enterprise class drives. With cheap/consumer drives you won't get the performance, reliability ...

The Adaptec RAID 1225SA is great, highly recommend it for W2K8.

I've had some compatibility issues with eSATA drives - had a few where the drive was fine when internally connected but just wouldn't work over eSATA. The drives in question were the first Seagate Free Agent external units to come with eSATA interfaces so this may just have been a technology maturity thing but it's worth checking that the external drive you ...

Not with common hardware. the eSATA ports you have are 'host' type, not 'device'. These days iSCSI is very efficient, thanks to optimized drivers that offload most of TCP handling to the card itself. Don't dismiss it without trying. Another alternative (that i use very successfully) is AoE. Just run vBlade on your 'target' nodes, the drivers are already ...

Are the eSATA channels logically separate from the internal channels? You might be plugging two drives into a single controller and ending up with data corruption as a result. Do you have any specific error codes? Why specifically does Windows not boot?

Have you considered the 3ware 9650SE-24M8? I believe it supports 2 TB drives but am not sure about Sil3726 compatibility. You should read some reviews on it especially since it will run you about $1000. Also two 12 port cards may be less than one 24 port card and may give you better performace, too.


1

Adaptec confirmed that their hardware does not support the SIL3726, so I would not go with that card. I myself is having a similiar issue as the OP, by the looks of it, the highpoint 27xx series seem to be the only "high" end manufacturer that states on their website support for PM. It is such a nice technology that I whish more high end raid controllers ...

You have several options. You could use 2.5" nearline SAS drives with capacities up to 1TB. You could also convert your ML350 to accommodate the large form-factor disks. Refer to the ML350 G6 quickspecs, but it should be possible to shift to LFF drives.

While not fundamentally impossible, I don't believe that any solution do to this exists. Firstly, if I'm understanding your request correctly -- the media player doesn't have it's own disk, or isn't using it here -- the media player expects to be presented a disk over eSATA. eSATA is a block-access protocol; to give it such a block device (a disk, that here ...

You should be able to achieve what you need with udev rules. You could create /dev symlinks to provide consistant access to your external drives (as identified by serial/model/etc). Those could then be referenced in the smartd config and marked with -d removable to ensure smartd starts up when the external drive is absent. You may still need to restart ...

The kernel option is CONFIG_SATA_PMP=y Not sure if Arch has that in its default kernel. However, tagram's line of questioning may be correct. It's possible your enclosure is making a raid (or JBOD) array of your disks. This will present as a single disk. Sizes will be different than a single disk unless it's making a more than 2 disk raid1.

Do you mean, an HP MSA 60 Array Enclosure? And for cables, you're probably referring to an external multilane SAS SFF-8088 connector. If so, then depending on which HP Smart Array RAID controller you're using, you can cascade up to three additional MSA 60 shelves off of one unit by using one port as IN (4) and the other as OUT (5). Cascading - The MSA60 ...

The method you discuss is commonly done on workstations, less on servers (and is not considered a pro approach on servers at all, barely on wksns) Steps: add 1 tb sata drive to server, internal or external do file backup and/or image backup to the sata drive in event of failure, connect the drive (internally or externally) to new server restore from sata ...
