it運維: solaris中添加刪除磁盤和分區(qū)

3月17日我們分享了一篇文章,”無企業(yè),不上云”,被各大平臺轉(zhuǎn)載分享,這讓我們看到了互聯(lián)網(wǎng)的熱情,也看到了企業(yè)對上云的渴望,艾銻無限作為阿里云的戰(zhàn)略合作伙伴,我們更樂意幫助企業(yè)上云,讓更多的企業(yè)邁向數(shù)字化時代.
 
我們相信每一家企業(yè)都是IT企業(yè),每一家企業(yè)都是互聯(lián)網(wǎng)企業(yè),每一家企業(yè)都是數(shù)字化企業(yè),這一切的基礎(chǔ)都是基于云,云將會成為企業(yè)最重要的基礎(chǔ)設(shè)施,就像水、媒、電一樣的重要.IT外包 那為什么云對于企業(yè)來說如此重要呢,主要有以下五個方面:

1、應(yīng)變力
云端快速部署、自由擴(kuò)展的優(yōu)勢，使網(wǎng)站、APP等應(yīng)用上線、迭代更加靈活，提高了信息系統(tǒng)的運營效率。云以突出的應(yīng)變能力，適應(yīng)多變的企業(yè)信息化進(jìn)程，降低試錯成本，加快研發(fā)進(jìn)度，增強(qiáng)企業(yè)創(chuàng)新的信心。

2、穩(wěn)定性
云環(huán)境為企業(yè)業(yè)務(wù)創(chuàng)造了一個穩(wěn)定、可靠的空間，使用戶體驗更好，客戶滿意度顯著提升。互聯(lián)網(wǎng)產(chǎn)品獲得流量和用戶粘性的核心是用戶體驗，在線用戶流暢訪問，便捷操作，才會有較高的市場占有率。

3、性價比
云計算優(yōu)異的性價比，為企業(yè)信息化大幅降低了成本。使企業(yè)可以把更多的資金，投入到業(yè)務(wù)創(chuàng)新中。傳統(tǒng)企業(yè)轉(zhuǎn)型升級存在著大量的不確定性，低成本的云計算幫助企業(yè)消除了資金上的顧慮。

4、安全性

轉(zhuǎn)型中的傳統(tǒng)企業(yè)，因?qū)W(wǎng)絡(luò)環(huán)境不熟悉，擔(dān)心網(wǎng)絡(luò)攻擊、數(shù)據(jù)泄露等安全問題。云計算服務(wù)商有專業(yè)的技術(shù)和高效的服務(wù)體系，幫助企業(yè)保護(hù)數(shù)據(jù)安全、規(guī)避安全風(fēng)險和提供海量數(shù)據(jù)查詢，企業(yè)可以專注于網(wǎng)站和應(yīng)用程序，而不是基礎(chǔ)設(shè)施。
 
5、擴(kuò)展性
 
在企業(yè)信息化的成本結(jié)構(gòu)中，購買硬件軟件成本占比很高，而實際用于開發(fā)的支出就相應(yīng)很低，并且耗費時間較長。如果完全基于云開架設(shè)IT系統(tǒng)，幾個小時就可完成基本框架。如果業(yè)務(wù)增加，就是直接購買服務(wù)器，邊際效益很低，采用云后，由于云計算的高擴(kuò)展性，通過邊際效益可實現(xiàn)成本下降。 綜上所述,未來云就像我們用的水、電、媒一樣成為企業(yè)的必須品,也會是最重要的基礎(chǔ)設(shè)施一個部分,所以數(shù)字化轉(zhuǎn)型的企業(yè),首先要上云,再考慮如何整合和重構(gòu)企業(yè)內(nèi)部的數(shù)據(jù),從而讓計算起到主導(dǎo)作用,最終實現(xiàn)企業(yè)數(shù)字化轉(zhuǎn)型終極目標(biāo).
 

solaris中添加刪除磁盤和分區(qū)

如何在solaris中添加刪除磁盤和分區(qū)
建意你先看 IDE 和 SCSI 分配名稱

以下例子是格式化 Primary IDE Master 硬盤

查看 IDE 和 SCSI 分配名稱后，我們知道 Primary IDE Master 硬盤名稱是c0d0。

請先行 Login 成為 root user

# drvconfig ( configure the /devices directory )
# disks ( creates /dev entries for hard disks attached to the system )
# format
Searching for disks...done

AVAILABLE DISK SELECTIONS:
0. c0d0
/pci@0,0/pci-ide@7,1/ide@0/cmdk@0,0
1. c1t6d0
/pci@0,0/pci9004,8178@f/sd@6,0
Specify disk (enter its number): 0 ( 因為 Primary IDE Master 硬盤名稱是c0d0，所以選擇 0 )

AVAILABLE DRIVE TYPES:
0. other
Specify disk type (enter its number):0
( 正常應(yīng)該是 0. DEFAULT 1. other，通常應(yīng)該選擇DEFAULT，但是Solaris不明白我的硬盤是什么，所

以只有other可供選擇。)

我的IDE HardDisk架構(gòu)如下:-
( 可以從BIOS Auto Detect查出來，通常都有LBA,LARGE,AUTO三種選擇，建意你使用Auto，因為不能大

過16Heads和不能大過63Sectoes )
Cylinders = 25232
Heads = 16

Enter number of data cylinders:25232
