Dear Friends,
I need to configure T5240 with Internal SAS RAID HBA(SG-XPCIESAS-R-INT-Z).. T5240 uses 8 hard disks... From the documents of RAID card I have found that I need to create a jump start server to include three packages SUNWaac, StorMan, SUNWgccruntime if Im using solaris10 5/08...

We have a dual-controller StorEdge 3320 disk array with 5 disks (each 320 MB). Four disks have been set up in a RAID-5 configuration with the remaining disk acting as a hot spare. There is a single logical drive which has been partitioned into 3 slices.
The disk array is to be simultaneously... (14 Replies)
May I know how can I add a new SSA pdisk into array and become usable hdisk? I have inserted a 36GB SSA disk into enclosure and done the "cfgmgr" and I can see it already been regconized as pdisk47.
I would like to make it a system disk in order for me to add to my volume group. Please let me... (3 Replies)
Hi,
I`m on SunFire480R with Solaris 10. Disk in rootdg group failed, so it was replaced. However, I cannot make Veritas initalise the replaced disk:
# vxdctl enable
# vxdisk list c1t0d0s2
Device: c1t0d0s2
devicetag: c1t0d0
type: auto

Hi,
Is there an easy way to find the disk-type from the command line or with another api ? sdparm works for SAS but not for SATA, hdparm works for SATA but not SAS.
Thanks (1 Reply)
Hi,
a little while ago, one of the GPT Partitioned hard disk had gone faulty in a Mirror RAID and is now successfully replaced.
here is how I did that.
1) created identical partition table on the new disk.
2) attached the mirrors using md commands.

I need to add a VMware virtual disk to the 99-oracle-asmdevices.rules file but the OS is not assigning a WWID to the disk. It has been fdisk'd and a single partition created.
What TAG inside the file needs to be added? the Program scsi-id does not work for some reason. latest patches... (0 Replies)
Hello,
On 4/20/2018, we performed a disk replacement on our IBM 8202 P7 server. After the disk was rebuilt, the SAS Disk Array sissas0 showed a status of degraded. However, the pdisks in the array all show a status of active.
We did see a message in errpt. DISK ARRAY PROTECTION SUSPENDED.

Hello,
I would like to check how many SAS disks and its size per disk for the whole power system. As per my understanding, if we assign the SAS controller to LPAR, then we can see the disk in lpar smitty command.
How can we check from the Power machine(physical ones) as well? I think the... (5 Replies)

pdisk
PDISK(8) BSD System Manager's Manual PDISK(8)NAME
pdisk -- Apple partition table editor
SYNOPSIS
pdisk [-h | --help] [-v | --version] [-l | --list] [[name ...]]
pdisk [r | -readonly] device ...
DESCRIPTION
pdisk is a menu driven program which partitions disks using the standard Apple disk partitioning scheme described in "Inside Macintosh:
Devices". It does not support the intel/dos partitioning scheme supported by fdisk.
device is of the following form:
/dev/disk0s
/dev/disk0s1
etc.
OPTIONS -v | --version
Prints version number of the pdisk program.
-h | --help
Prints a rather lame set of help messages for the pdisk program.
-l | --list
If no names are present then lists the partition tables for /dev/disk0s, /dev/disk0s1, /dev/disk0s2, and so on. Otherwise, lists
the partition tables for the specified names.
-r | --readonly
Prevents pdisk from writing to the device.
Editing Partition Tables
An argument which is simply the name of a device indicates that pdisk should edit the partition table of that device.
The current top level editing commands are:
h command help
p print the partition table
P (print ordered by base address)
i initialize partition map
s change size of partition map
c create new partition
C (create with type also specified)
d delete a partition
r reorder partition entry in map
w write the partition table
q quit without saving changes
Commands which take arguments prompt for each argument in turn. You can also type any number of the arguments separated by spaces and those
prompts will be skipped. The only exception to typeahead are the confirmation prompts on the i and w commands. The idea being that if we
expect you to confirm the decision we shouldn't undermine that by allowing you to be precipitate about it.
Partitions are always specified by their number, which the index of the partition entry in the partition map. Most of the commands will
change the index numbers of all partitions after the affected partition. You are advised to print the table as frequently as necessary.
Creating more than fifteen partitions is not advised. There is currently a bug in the some (all?) of the kernels which causes access to the
whole disk fail if more than fifteen partitions are in the map.
The c (create new partition) command is the only one with complicated arguments. The first argument is the base address (in blocks) of the
partition. Besides a raw number, you can also specify a partition number followed by the letter 'p' to indicate that the first block of the
new partition should be the same as the first block of that existing free space partition. The second argument is the length of the parti-
tion in blocks. This can be a raw number or can be a partition number followed by the letter 'p' to use the size of that partition or can be
a number followed by 'k', 'm', or 'g' to indicate the size in kilobytes, megabytes, or gigabytes respectively. (These are powers of 1024, of
course, not powers of 1000.) The last argument is the name of the partition. This can be a single word without quotes, or a string sur-
rounded by single or double quotes.
The C command is identical to the c command, with the addition of a partition type argument after the other arguments.
The r (reorder) command allows the index number of partitions to be changed. The index numbers are constrained to be a contiguous sequence.
The i (initialize) command prompts for the size of the device. This was done to get around a bug in the kernel where it reports the wrong
size for the device.
The w (write) command does write the partition map out.
BUGS
pdisk should be able to create HFS partitions that work.
Even more help should be available during user input.
