Solaris 系统最大可支持多大的硬盘

liusr

我的riad是ibm的，3t，在sun上做盘，可系统最大只认752gb，原分区是1.3t和1.4t。Solaris 系统最大可支持多大的硬盘???请指教。谢谢！！

用EFI格式，大于1T没有问题。

我是新手，请讲细一些，谢谢。

Solaris 2.8 支持EFI格式吗？

DIFFERENCES (EFI versus VTOC)

Supported by 64-bit Solaris[TM] 9 Operating System (04/03) and above only (no x86 support, no backporting yet).

Provides support for disks greater than 1 terabyte in size.

Provides 7 useable slices - 0 thru 6 - where slice 2 is just another slice.

Solaris[TM] ZFS (Zettabyte File System) uses EFI labels by default.

Partitions (or slices) cannot overlap with the primary or backup label, or with any other partitions. The size of the EFI label is usually 34
sectors, so partitions start at sector 34. This feature means no partition can start at sector zero (0).

No cylinder or head information is stored in the label. Sizes are reported in sectors and blocks.

Information that was stored in the alternate cylinders area, the last two cylinders of the disk, is now stored in slice 8.

If you use the "format" utility to change partition sizes, the unassigned partition tag is assigned to partitions with sizes equal to zero. By default, the "format" utility assigns the "usr" partition tag to any partition with a size greater than zero. You can use the "partition change" menu to reassign partition tags after the partitions are changed. However, you cannot change a partition with a non-zero size to the "unassigned" partition tag.

EFI labels CAN be written to disks smaller than 1TB, where a standard VTOC label would normally apply, but VTOC cannot be forced onto devices larger than 1TB with. This can be done by running "format -e". When you attempt to "label" the disk, you will be asked which type of label is to be written.

RESTRICTIONS

The layered software products not intended for systems with EFI-labeled disks might be incapable of accessing a disk with an EFI disk label. (i.e., current VxVM versions) " A disk with an EFI disk label is not recognized on systems running previous Solaris Operating System releases. Adding an EFI-labeled disk to a system that does not support it will result in messages simlar to the following:

   Dec 3 09:12:17 <hostname> scsi: WARNING:
      /sbus@a,0/SUNW,socal@d,10000/sf@1,0/ssd@w50020f23000002a4,0 (ssd1): corrupt label - wrong magic number


You cannot boot from a disk with an EFI disk label.

You cannot use the Solaris[TM] Management Console's Disk Manager Tool to manage disks with EFI labels. Use the "format" utility or the Solaris Management Console's Enhanced Storage Tool to manage disks with EFI labels, after you use the 'format' utility to partition the disk.

The EFI specification prohibits overlapping slices. The whole disk is represented by "c#t#d#p6". For example:

    lrwxrwxrwx 1 root root 70 Nov 25 18:54 c8t1d0p6 ->
                 ../../devices/.../ssd@w50020f23000004aa,0:wd


The following format options are not applicable on disks with EFI labels:

The "save" option is not supported because disks with EFI labels do not need an entry in the "format.dat" file.

The "backup" option is not applicable because the disk driver finds the primary label and writes it back to the disk.

SIDE BY SIDE COMPARISON

This example uses a standard internal 9GB drive (Fujitsu MAG3091L, Sun firmware). First, we view the existing disk label via 'format':

  Current partition table (original):
  Total disk cylinders available: 4924 + 2 (reserved cylinders)
  Part     Tag  Flag Cylinders       Size         Blocks
  0       root   wm   0 - 2586       4.43GB   (2587/0/0)  9289917
  1 unassigned   wm   0              0        (0/0/0)           0
  2     backup   wm   0 - 4923       8.43GB   (4924/0/0) 17682084
  3 unassigned   wm   0              0        (0/0/0)           0
  4 unassigned   wm   0              0        (0/0/0)           0
  5 unassigned   wm   0              0        (0/0/0)           0
  6 unassigned   wm   0              0        (0/0/0)           0
  7 unassigned   wm   4917 - 4922    10.52MB  (6/0/0)       21546


Now, after using 'format -e' option to write EFI label-

  Current partition table (original):
  Total disk sectors available: 17672849 + 16384 (reserved sectors)
  Part     Tag  Flag  First Sector    Size       Last Sector
  0       root   wm             34    4.43GB         9289916
  1       swap   wu        9289917    3.99GB        17656946
  2 unassigned   wm              0    0                    0
  3 unassigned   wm              0    0                    0
  4 unassigned   wm              0    0                    0
  5 unassigned   wm              0    0                    0
  6 unassigned   wm              0    0                    0
  8   reserved   wm       17672849    8.00MB        17689232


The look and feel from the format is different two, the standard vtoc presents the size in the format cylinder/head/sector whereas an EFI label only gives the available blocks in hexadezimal.

     17. c6t20000020372651C5d0 <SEAGATE  ST39102FCSUN9.0G 0D29 10deab3>
         /scsi_vhci/ssd@g20000020372651c5
     18. c6t20000020372650C5d0 <SUN9.0G cyl 4924 alt 2 hd 27 sec 133>
         /scsi_vhci/ssd@g20000020372650c5


As you can see, the EFI lable informs you about the vendor and model of the disk drive and the standard vtoc calls it only a SUN9.0G disk drive.
