Adaptec 29320LPE支援>2T的LUN嗎....

鵝有個user很精實,想拿29320LPE接7T的storage,他說在SCSI BIOS中的確只看到一個7T的LUN,但是OS開起來後kernel看到的卻是4個1.7T的LUN,鵝找了一下Adaptec最後一版的FW也到2009年為止(i.e.很有可能不支援>2T的LUNOrz),請問一下有邦友這麼用過嗎疑惑疑惑....

鵝把linux kernel由2.6.18升到2.6.39,同時確定有支援GPT,但還是抓成4個LUN,而且SCSI卡看到SCSI BUS是長這樣的Orz....

上網找了張LSI 53C1030的拆機卡,今天拿去送給user,換完就ok了,總算不用再被盧了OrzOrz...

38655: Adaptec SCSI Card ASC-29320LPE Single這篇說有支援 over 2TB

由於 BIOS 內看到 7TB, 而 OS 看不到, 所以要查您的 OS 是否用 UEFI 安裝的?
沒用 UEFI mode 的話, OS 開機碟無法超過 2TB, 即使 LUN 可以看到 7TB 也沒用.

看更多先前的回應...收起先前的回應...

這個7T的LUN只是要當storage用而已,OS是裝在其它MBR格式的HD上,不過有網友說CentOS5.5的kernel並不支援GPT,看樣子得幫user加工了....

真的假的

"Using GPT

Three main classes of software all require GPT support: the kernel, the boot loader, and low-level disk utilities. If you're using GPT because you're setting up a large redundant array of independent disks (RAID) array, you may also need to look into file system support for extra-large disks.

Note: If you're installing Linux from scratch and want to use GPT, your installer must provide GPT support in all three of these categories. In 2012, this support is present in all the major Linux distributions. "

CentOS5.5好像是2010年出的,如果是這樣default不支援GPT好像也是正常的偷笑偷笑....

Adaptec SCSI Card 29320LPE 是non-UEFI-compliant adapter:
These systems won't boot at all with a non-UEFI compliant Adaptec product installed.

不出版大所料:
The total size of an array or single disk cannot exceed 2TB (two terrabytes) for the SCSI HostRAID controllers (i.e. 29320A-R, 39320-R, etc.).

OS是放在另一顆小HD上的,這個7T的LUN只是要當storage而已

Linux 2.6 kernels support arrays larger than 2TB in capacity.
With the remaining capacity of the array (>2TB), you must use the ‘parted’ command as the disk-partitioning tool, not ‘fdisk’. Once you have used the ‘parted’ command, you will be able to access it as one whole volume.
有關beyond 2T,有網友問到29320LPE,可是沒郎哉...

鵝有前同事說他在別的site有遇過29320LPE配>2T storage沒問題的,怕是user的SCSI BIOS太舊或是在SCSI BIOS中設了將>2T的storage切成multi LUN了,不過這部份遠端看不到,所以只好找時間跑一趟了OrzOrz....

BIOS Multiple LUN Support—(Default: No) Leave this setting at No if the device does not have multiple LUNs. When set to Yes, the SCSI card BIOS provides boot support for a SCSI device with multiple LUNs .
