Automating partitioning setup of /dev/sda on /dev/sdc
Objective: To recreate the partitioning setup of /dev/sda on /dev/sdc
How would I parse the below information and initialize variables
(an array?) that can be used to build sgdisk commands in a script, regardless of the number of partitions?
for each partition listed in text produced by an sgdisk - i command.
I am thinking that I can save this text to a file in the backup process and then use it in the restoration process...
Thank you vey much in advance for any time and effort expended in answering my
question!
Code:
root@redbrick /: sgdisk -p /dev/sda
Disk /dev/sda: 1465149168 sectors, 698.6 GiB
Logical sector size: 512 bytes
Disk identifier (GUID): 3A4C6201-749A-4B13-93E0-A94B52349823
Partition table holds up to 128 entries
First usable sector is 34, last usable sector is 1465149134
Partitions will be aligned on 2048-sector boundaries
Total free space is 749229 sectors (365.8 MiB)
Number Start (sector) End (sector) Size Code Name
1 2048 411647 200.0 MiB EF00 EFI System Partition
2 411648 1435647 500.0 MiB 8300
3 1435648 1464401919 697.6 GiB 8300

So, we removed a LUN from the SAN and the system is refusing to remove the references to it in the /dev folder. I've done the following:

luxadm -e offline <drive path>
luxadm probe
All those commands failed to remove the path. The drive stills shows up as <drive... (13 Replies)

Hello AIXians,
I can't boot my AIX, it hangs and stops at the code error: 0518
After searching google, I knew the problem is due to problems in File Systems.

HD(4) Linux Programmer's Manual HD(4)NAME
hd - MFM/IDE hard disk devices
DESCRIPTION
The hd* devices are block devices to access MFM/IDE hard disk drives in raw mode. The master drive on the primary IDE controller (major
device number 3) is hda; the slave drive is hdb. The master drive of the second controller (major device number 22) is hdc and the slave
hdd.
General IDE block device names have the form hdX, or hdXP, where X is a letter denoting the physical drive, and P is a number denoting the
partition on that physical drive. The first form, hdX, is used to address the whole drive. Partition numbers are assigned in the order
the partitions are discovered, and only non-empty, non-extended partitions get a number. However, partition numbers 1-4 are given to the
four partitions described in the MBR (the `primary' partitions), regardless of whether they are unused or extended. Thus, the first logi-
cal partition will be hdX5. Both DOS-type partitioning and BSD-disklabel partitioning are supported. You can have at most 63 partitions
on an IDE disk.
For example, /dev/hda refers to all of the first IDE drive in the system; and /dev/hdb3 refers to the third DOS `primary' partition on the
second one.
They are typically created by:
mknod -m 660 /dev/hda b 3 0
mknod -m 660 /dev/hda1 b 3 1
mknod -m 660 /dev/hda2 b 3 2
...
mknod -m 660 /dev/hda8 b 3 8
mknod -m 660 /dev/hdb b 3 64
mknod -m 660 /dev/hdb1 b 3 65
mknod -m 660 /dev/hdb2 b 3 66
...
mknod -m 660 /dev/hdb8 b 3 72
chown root:disk /dev/hd*
