StorCLI Command Cheat Sheet

StorCLI adalah command-line utility untuk mengelola storage controllers LSI/Broadcom MegaRAID, memungkinkan kontrol penuh atas drive fisik dan virtual, konfigurasi RAID, dan diagnostik sistem. Tool ini menggunakan sintaks hierarkis dengan pengidentifikasi seperti /c0 untuk controller 0, /e0 untuk enclosure, and /s0 untuk slot. Sebagian besar perintah mendukung operasi show, set, dan delete, dan menambahkan J di akhir akan menghasilkan output dalam format JSON.

🔹 Quick Health & Error Check

#

storcli /c0 /eall /sall show
storcli /c0 /e252 /sall show all
storcli /c0 /eall /sall show all | egrep "Slot Number|State|Media Error Count|Other Error Count|Predictive Failure Count"

Controller & System Overview

#

• List all controllers:

storcli /call show

• Show detailed controller information:

storcli /c0 show all

• Display system overview (controllers, drives, health):

storcli show

• Show firmware, model, and serial number:

storcli /c0 show

Physical Drives

#

• Show all physical drives:

storcli /call/dall show

• Show detailed info for all physical drives:

storcli /call/dall show all

• Show drives in specific enclosure (example: enclosure 252):

storcli /c0/e252/sall show

• Show specific drive (enclosure 252, slot 0):

storcli /c0/e252/s0 show

Virtual Drives

#

• List all virtual drives:

storcli /call/vall show

• Show detailed info for virtual drive 0:

storcli /c0/v0 show

• Show virtual drive properties in JSON format:

storcli /c0/v0 show J

• Show initialization status:

storcli /c0/v0 show init

RAID Management

#

Create RAID Arrays

#

• Create RAID 1 (mirror) with 2 drives:

storcli /c0 add vd r1 drives=252:0,252:1

• Create RAID 5 with drives slot 0–7:

storcli /c0 add vd r5 drives=252:0-7

• Create RAID 10 with 8 drives (2 drives per array):

storcli /c0 add vd r10 drives=252:0-7 pdperarray=2

Delete Virtual Drives

#

• Delete all virtual drives on controller 0:

storcli /c0/vall delete force

⚠️ WARNING: This will destroy all data.

RAID Migration / Expansion

#

• Expand RAID 5 by adding a new drive:

storcli /c0/v0 start migrate type=raid5 option=add drives=252:8

Tips & Best Practices:

• Always check Media Error Count and Predictive Failure Count before replacing disks.
• Use show all for full SMART-like detail.
• RAID migration can take hours to days depending on disk size and load.
• Backup before RAID operations.

Disk & Enclosure Operations

#

Locate / Identify Disk

#

• Blink LED untuk identifikasi disk:

storcli /c0/e252/s0 start locate

• Matikan LED locate:

storcli /c0/e252/s0 stop locate

Mark Disk as Failed / Missing (Untuk Replacement)

#

• Mark disk sebagai failed (manual fail):

storcli /c0/e252/s0 set failed

• Mark disk sebagai offline:

storcli /c0/e252/s0 set offline

Replace Failed Drive & Rebuild

#

1. Replace disk secara fisik
2. Start rebuild (biasanya otomatis jika hot spare atau RAID policy mendukung)

Manual rebuild:

storcli /c0/e252/s0 start rebuild

Correct replacement workflow:

storcli /c0/e252/s0 set failed
# Replace disk physically
storcli /c0/e252/s0 start rebuild

Clear Foreign Configuration

#

storcli /call/fall delete

Controller Settings

#

• Enable JBOD mode:

storcli /c0 set jbod=on

• Disable JBOD mode:

storcli /c0 set jbod=off

• Set rebuild rate (30%):

storcli /c0 set rebuildrate=30

• Enable alarm:

storcli /c0 set alarm=enbl

• Silence alarm:

storcli /c0 set alarm=silence

Diagnostics & Maintenance

#

• Show BBU status:

storcli /c0/bbu show

• Show CacheVault info:

storcli /c0/cv show

• Show enclosure info:

storcli /c0/eall show

• Show event logs:

storcli /c0 show events

• Clear event logs:

storcli /c0 delete events

• Start patrol read:

storcli /c0 start patrolread

Advanced Operations

#

Initialize Virtual Drive

#

• Full initialization:

storcli /c0/v0 start init full

• Force init (⚠️ DESTROYS DATA):

storcli /c0/v0 start init full force

• Show init progress:

storcli /c0/v0 show init

Cache Policy

#

• Set cache policy (WriteBack + ReadAhead):

storcli /c0/v0 set wrcache=WB rdcache=RA

Common options:

• WB / WT → Write Back / Write Through
• RA / NR → Read Ahead / No Read Ahead

Global Hot Spare

#

• Set drive as global hot spare:

storcli /c0/e252/s1 add hotsparedrive
